SEMICONDUCTOR TECHNICAL DATA
LOW–VOLTAGE CMOS
16–BIT TRANSCEIVER/
REGISTERED TRANSCEIVER
WITH DUAL ENABLE
The MC74LCX16652 is a high performance, non–inverting 16–bit
transceiver/registered transceiver operating from a 2.7 to 3.6V supply.
The device is byte controlled. Each byte has separate control inputs
which can be tied together for full 16–bit operation. High impedance TTL
compatible inputs significantly reduce current loading to input drivers
while TTL compatible outputs offer improved switching noise
performance. A V specification of 5.5V allows MC74LCX16652 inputs to
I
be safely driven from 5V devices. The MC74LCX16652 is suitable for
memory address driving and all TTL level bus oriented transceiver
applications.
Data on the A or B bus will be clocked into the registers as the
appropriate clock pin goes from a LOW–to–HIGH logic level. Output
Enable pins (OEBAn, OEABn) are provided to control the transceiver
outputs. In the transceiver mode, data present at the high impedance port
may be stored in either the A or the B register or in both. The select
controls (SBAn, SABn) can multiplex stored and real–time (transparent
mode) data. In the isolation mode (both outputs disabled), A data may be
stored in the B register or B data may be stored in the A register. When in
the real–time mode, it is possible to store data without using the internal
registers by simultaneously enabling OEAB and OEBA. In this
configuration, each output reinforces its input (data retention is not
guaranteed in this mode).
