GENERAL DESCRIPTION
The ADG1604 is a complementary metal-oxide semiconductor (CMOS) analog multiplexer and switches one of four inputs to a common output, D, as determined by the 3-bit binary address lines, A0, A1, and EN. Logic 0 on the EN pin disables the device. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
The ultralow on resistance of these switches make them ideal solutions for data acquisition and gain switching applications where low on resistance and distortion is critical. The on resistance profile is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals.
The CMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments.

*0.2 Ω on resistance flatness
*±3.3 V to ±8 V dual supply operation
*3.3 V to 16 V single supply operation

DESCRIPTION
The MC74VHC4066 utilizes silicon–gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF–channel leakage current. This bilateral switch/multiplexer/demultiplexer controls analog and digital voltages that may vary across the full power–supply range (from VCC to GND).
The VHC4066 is identical in pinout to the metal–gate CMOS MC14066 and the high–speed CMOS HC4066A. Each device has four independent switches. The device has been designed so that the ON resistances (RON) are much more linear over input voltage than RON of metal–gate CMOS analog switches.
The ON/OFF control inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. For analog switches with voltage–level translators, see the VHC4316.

FEATURES
*Fast Switching and Propagation Speeds
*High ON/OFF Output Voltage Ratio
*Low Crosstalk Between Switches
*Diode Protection on All Inputs/Outputs
*Wide Power–Supply Voltage Range (VCC – GND) = 2.0 to 12.0 Volts
*Analog Input Voltage Range (VCC – GND) = 2.0 to 12.0 Volts
*Improved Linearity and Lower ON Resistance over Input Voltage than the MC14016 or MC14066
*Low Noise
*Chip Complexity: 44 FETs or 11 Equivalent Gates

DESCRIPTION
The MC74VHCT4051 utilizes silicon–gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. This analog multiplexer/demultiplexer controls analog voltages that may vary across the complete power supply range (from VCC to GND).
The VHCT4051 is identical in pinout to the high–speed HC4051A and the metal–gate MC14051B. The Channel–Select inputs determine which one of the Analog Inputs/Outputs is to be connected by means of an analog switch to the Common Output/Input. When the Enable pin is HIGH, all analog switches are turned off.
The Channel–Select and Enable inputs are compatible with TTL–type input thresholds. The input protection circuitry on this device allows overvoltage tolerance on the input, allowing the device to be used as a logic–level translator from 3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic while operating at the higher–voltage power supply.
The MC74VHCT4051 input structure provides protection when voltages up to 7V are applied, regardless of the supply voltage. This allows the MC74VHCT4051 to be used to interface 5V circuits to 3V circuits.
This device has been designed so that the ON resistance (Ron) is more linear over input voltage than Ron of metal–gate CMOS analog switches.
For a multiplexer/demultiplexer with channel–select latches, see VHC4351.

FEATURES
*Fast Switching and Propagation Speeds
*Low Crosstalk Between Switches
*Diode Protection on All Inputs/Outputs
*Analog Power Supply Range (VCC – GND) = 2.0 to 6.0 V
*Digital (Control) Power Supply Range (VCC – GND) = 2.0 to 6.0 V
*Improved Linearity and Lower ON Resistance Than Metal–Gate Counterparts
*Low Noise
*In Compliance With the Requirements of JEDEC Standard No. 7A

Organization and Application
The ACT8502 consists of six 16 channel muxes arranged as shown in the Block Diagram.
The ACT8502 design is inherently Radiation Hard due to the HS1840RH Multiplexers as well as
Microsemi Corp.
Transient Suppressors (Reference Microsemi MicroNotes Series 050 - page 14).
48 channels addressable by Bus A0~A3, in Three 16 channel blocks, each block enabled
separately.
Each block connects the addressed channel to two outputs, "Output" and "Current".
This technique enables selecting and reading a remote resistive sensor without the MUX
resistance being part of the measurement.
For grounded sensors, this is done by passing current to the sensor by means of the "Current" pin and reading the resultant voltage (proportional to the sensor resistance) at the "Output" pin.
NOTE: It is recommended that all "NC or "no connect pin", be grounded.
This eliminates or minimizes any ESD or static buildup.

Description
 The GS1582 is the next generation multi-standard serializer with an integrated cable driver.
The device provides robust parallel to serial conversion, generating a SMPTE 292M/259M-C compliant serial digital output signal.
The integrated cable driver features an output disable (high impedance) mode and an adjustable signal swing.
Data input is accepted in 20-bit parallel format or 10-bit parallel format. An associated parallel clock input must be provided at the appropriate operating frequency; 74.25/74.1758/13.5MHz (20-bit mode) or 148.5/148.352/27MHz (10-bit mode).
The GS1582 features an internal PLL which, if desired, can be configured for a loop bandwidth below 100kHz.
When used in conjunction with the GO1555 Voltage Controlled Oscillator, the GS1582 can tolerate well in excess of 300ps jitter on the input PCLK and still provide output jitter within SMPTE specifications.
In addition to serializing the input, the GS1582 performs NRZ-to-NRZI encoding and scrambling as per SMPTE 292M/259M-C when operating in SMPTE mode.
When operating in DVB-ASI mode, the device will insert K28.5 sync characters and 8b/10b encode the data prior to serialization.
The device also provides a range of other data processing functions.
All processing features are optional and may be enabled/disabled via external control pin(s) and/or host interface programming.
The GS1582 can embed up to 8 channels of audio into the video data stream in accordance with SMPTE 299M and SMPTE 272M.
The audio input signal formats supported by the device include AES/EBU and I2S serial digital formats with a 16, 20 or 24 bit sample size and a 48 kHz sample rate.
Additional audio processing features include individual channel enable, channel swap, group swap, ECC generation and audio channel status insertion.
Typical power consumption, including the GO1555 VCO, is 500mW.
The standby feature allows the power to be reduced to 125mW.
Power may be reduced to less than 10mW by also removing the power to the cable driver and eliminating transitions at the parallel data and clock inputs.
The GS1582 is Pb-free and RoHS compliant.
