Product Description

Pericom Semiconductor’s PI74LPT series of logic circuits are pro-

duced in the Company’s advanced 0.6 micron CMOS technology,

achieving industry leading speed grades.

The PI74LPT16646 is a 16-bit registered transceiver organized as

two independent 8-bit bus transceivers designed with 3-state

D-type flip-flops and control circuitry arranged for multiplexed

transmission of data directly from the data bus or from the internal

storage registers. Each 8-bit transceiver utilizes the enable control

(xOE) and direction pins (xDIR) to control the transceiver functions.

The Select (xSAB and xSBA) control pins are used to select either

real-time or stored data transfer. The circuitry used for select control

will eliminate the typical decoding glitch that occurs in a multiplexer

during the transition between real-time and stored data. A low input

level selects real-time data and a high selects stored data.

The PI74LPT16646 can be driven from either 3.3V or 5.0V devices

allowing this device to be used as a translator in a mixed

3.3/5.0V system.
