DESCRIPTION
The 74LCX652 is a low voltage CMOS OCTAL
BUS
(3-STATE) fabricated with sub-micron silicon gate
and double-layer metal wiring C
It is ideal for low power and high speed 3.3V
applications; it can be interfaced to 5V signal
environment for both inputs and outputs.

Table 1: Order Codes
This device consists of bus transceiver circuits
with 3 state, D-type flip-flops, and control circuitry
arranged for multiplexed transmission of data
directly from the input bus or from the internal
storage registers. Enable (GAB) and (GBA) pins
are provided to control the transceiver functions.
Select AB and Select BA control pins are provided
to select whether real-time or stored data is
transferred. A low input level selects real-time,
and a high selects stored data.
Data on the A or B bus, or both, can be stored in
the internal D flip-flop by low to high transitions at
the appropriate clock pins (CAB or CBA)
regardless of the select or enable control pins.
When select AB and select BA are in the real-time
transfer mode, it is also possible to store data
