General Description
The EMC1033 is an SMBus temperature sensor that monitors up to three temperature zones and can generate two system interrupts. With ±1°C measurement accuracy, the EMC1033 provides a low-cost solution for critical temperature monitoring applications. Features include automatic resistance error correction and programmable ideality factor configuration eliminating both major sources of temperature measurement error.
The EMC1033 generates two separate interrupts with programmable thermal trip points. The THERM output operates as a thermostat with programmable threshold and hysteresis. The ALERT output can be configured as a maskable SMBus alert with programmable window comparator limits, or as a second THERM output. Both interrupts are maintained in an 8-pin package while a third temperature zone is added with the anti-parallel diode technique. This allows the EMC1033 to be pin compatible with the ADT7461, ADM1032, LM99, and the MAX6649 with the advantage of a third temperature zone.

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.
FEATURES
*1 Ω typical on resistance
*0.2 Ω on resistance flatness
*±3.3 V to ±8 V dual supply operation
*3.3 V to 16 V single supply operation
*No VL supply required
*3 V logic-compatible inputs
*Rail-to-rail operation
*Continuous current per channel
-LFCSP package: 504 mA

*Audio signal routing
*Video signal routing
*Automatic test equipment

The Intersil ISL84467 device is a low ON-resistance, low voltage, bidirectional, Quad SPDT (Dual DPDT) analog switch designed to operate from a single +1.65V to +4.5V supply.
Targeted applications include battery powered equipment that benefit from low rON (0.39Ω) and fast switching speeds (tON = 33ns, tOFF = 16ns).
The digital logic input is 1.8V logic-compatible when using a single +3V supply.
With a supply voltage of 4.2V and logic high voltage of 2.85V at both logic inputs, the part draws only 12μA max of ICC current.
Cell phones, for example, often face ASIC functionality limitations.
The number of analog input or GPIO pins may be limited and digital geometries are not well suited to analog switch performance.
This part may be used to “mux-in” additional functionality while reducing ASIC design risk.
The ISL84467 is offered in small form factor package, alleviating board space limitations.
The ISL84467 consists of four SPDT switches.
It is configured as a dual double-pole/double-throw (DPDT) device with two logic control inputs that control two SPDT switches each.
The configuration can be used as a dual differential 2-to-1 multiplexer/demultiplexer.
