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
