16-BIT LATCHED TRANSCEIVERS

PI74LPT16543

Fast CMOS 16-Bit Latched Transceivers

Product Features

ProductDescription

CompatiblewithLCXandLVTfamiliesofproducts

Pericom Semiconductors PI74LPT series of logic circuits are

produced using the Companys advanced 0.6 micron CMOS

technology, 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

ThePI74LPT16543is16-bitlatchedtransceiversorganizedwithtwo

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

data from xBx, as indicated in the Truth Table. With xCEAB LOW,

a LOW signal makes the A-to-B latches transparent; a subsequent

LOW-to-HIGHtransitionofthexLEABsignalputstheAlatchesin

the storage mode and their outputs no longer change the A inputs.

WithxCEABandxOEABbothLOW,the3-stateBoutputbuffersare

active and reflect the data present at the output of the A latches.

Advanced Low Power CMOS Operation

Excellent output drive capability:

Balanced drives (24 mA sink and source)

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

Multiple center pins and distributed Vcc/GND pins

minimize switching noise

allowing this device to be used as a translator in a mixed 3.3/5.0V

system.
