Product Description
Pericom Semiconductor's PI74LCX series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The PI74LCX16652 is 16-bit non-inverting, bidirectional bus
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 controls (xOEAB and x OEBA) 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 PI74LCX16652 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.
