PI74LPT162Q952

Fast CMOS 3.3V

16-Bit Registered Transceivers

ProductFeatures

ProductDescription

CompatiblewithLCXandLVTfamiliesofproducts

Pericom Semiconductors PI74LPT series of logic circuits are

producedintheCompanysadvanced0.6micronCMOStechnology,

achieving industry leading speed grades.

Supports 5V Tolerant Mixed Signal Mode Operation

Input can be 3V or 5V

Output can be 3V or connected to 5V bus

The PI74LPT162Q952 has 16-bit registered transceivers organized

with two sets of eight D-type latches with separate input and output

controls for each set. For data flow from A to B, for example, the

A-to-BEnable(xCEAB)inputmustbeLOWtoenterdatafromxAx.

xCLKABtogglesfromLOW-to-HIGH.ThexOEABcontrolperforms

the output enable function on the B port. Control of data from B to

Aissimilar, butusesthexCEAB, xCLKAB, andxOEABinputs. By

connecting the control pins of the two independent transceivers

together, a full 16-bit operation can be achieved. The output buffers

are designed with a Power-Off disable allowing live insertion of

boards when used as backplane drivers.

Advanced Low Power CMOS Operation

Excellentoutputdrivecapability:

Balanced drives (12mA sink and source)

25-Ohm Series resistor on outputs to reduce

overshoot and undershoot

Pin compatible with industry standard

double-density pinouts

Low ground bounce outputs

Hysteresis on all inputs

Industrial operating temperature range: 40°C to +85°C
