Description
The HFA5253 is a very high speed monolithic pin driver solution for high performance test systems. The device will switch at high data rates between two input voltage levels providing variable amplitude pulses. Slew Rate Control pins provide independent control over positive and negative slew rate allowing the customer to optimize the pin driver speed for their application. The output impedance is trimmed to achieve a precision 50Ω source for impedance matching.
Two differential ECL/TTL compatible inputs control the operation of the HFA5253, one controlling the VHIGH/VLOW switching and the other controlling the output’s highimpedance state. The HFA5253’s 800MHz data rate makes it compatible with today’s high-speed VLSI test systems and the +8V to -3V output swing satisfies the most stringent testing requirements of all common logic families.

Outline
These ICs were developed for STATIC-RAM (S-RAM) battery back-up, and have built-in switching circuit for main power supply and battery, back-up timing circuit and battery checker.
Power ON/OFF and momentary power interruptions can damage S-RAM data on equipment that contains an S-RAM. These ICs switch the S-RAM to back-up mode (CS signal makes S-RAM CE pin low and CE pin high)
when power supply voltage goes below a set voltage (detection voltage 4.2V typ., variable), preventing damage to data. Further, when power supply voltage drops, these ICs switch from main power supply to battery back-up (switching voltage 3.3V typ.). Then, when power supply voltage rises, they first switch the SRAM from battery back-up state to main power supply (switching voltage 3.3V typ.), and from back-up mode to normal mode (CS signal makes S-RAM CE pin high and CE pin low). These signal processes provide reliable protection against data damage. The CS signal also can absorb power supply chattering and roughness through the external capacitor.
There is a built-in battery checker to monitor the back-up battery voltage, and this circuit is turned ON/OFF by the control pin.

FUNCTIONAL DESCRIPTION
The 3D3424 device is a small, versatile, quad 4-bit programmable monolithic delay line. Delay values, programmed via the serial interface, can be independently varied over 15 equal steps. The step size (in ns) is determined by the device dash number. Each input is reproduced at the corresponding output without inversion, shifted in time as per user selection. For each line, the delay time is given by:
TDn = T0 + An * TI
where T0 is the inherent delay, An is the delay address of the n-th line and TI is the delay increment (dash number). The desired addresses are shifted into the device via the SC and SI inputs, and the addresses are latched using the AL input. The serial interface can also be used to enable/disable each delay line. The 3D3424 operates at 3.3 volts and has a typical T0 of 9ns. The 3D3424 is CMOS-compatible, capable of sourcing or sinking 4mA loads, and features both rising- and falling-edge accuracy. The device is offered in a standard 14-pin auto-insertable DIP and a space saving surface mount 14-pin SOIC.

FUNCTIONAL DESCRIPTION
The 3D7521 is a monolithic CMOS Manchester Encoder.
The clock and data, present at the unit input, are combined into a single bi-phase-level signal. In this encoding mode, a logic one is represented by a high-to-low transition within the bit cell, while a logic zero is represented by a low-to-high transition.
The unit operating baud rate (in Mbaud) is equal to the input clock frequency (in MHZ).
All pins marked N/C must be left unconnected.
The all-CMOS 3D7521 integrated circuit has been designed as a reliable, economic alternative to hybrid TTL Manchester Encoder.
It is TTL- and CMOS-compatible, capable of driving ten 74LS-type loads.
It is offered in space saving surface mount 8-pin and 14-pin SOICs.
The 3D7521 Manchester Encoder samples the data input at the rising edge of the input clock.
The sampled data is used in conjunction with the clock rising and falling edges to generate the by-phase level Manchester code.

FEATURES
* All-silicon, low-power CMOS technology
* TTL/CMOS compatible inputs and outputs
* Vapor phase, IR and wave solderable
* Low ground bounce noise

FUNCTIONAL DESCRIPTION
 The 3D7522 product family consists of monolithic CMOS Manchester Decoders.
The unit accepts at the RX input a bi-phase-level, embedded-clock signal.
In this encoding mode, a logic one is represented by a high-to-low transition within the bit cell, while a logic zero is represented by a low-to-high transition.
The recovered clock and data signals are presented on CLK and DATB, respectively, with the data signal inverted.
The operating baud rate (in MBaud) is specified by the dash number.
The input baud rate may vary by as much as ±15% from the nominal device baud rate without compromising the integrity of the information received.
Because the 3D7522 is not PLL-based, it does not require a long preamble in order to lock onto the received signal.
Rather, the device requires at most one bit cell before the data presented at the output is valid.
This is extremely useful in cases where the information arrives in bursts and the input is otherwise turned off.
The all-CMOS 3D7522 integrated circuit has been designed as a reliable, economic alternative to hybrid TTL Manchester Decoders.
It is TTL- and CMOS-compatible, capable of driving ten 74LS-type loads.
