SEMICONDUCTOR TECHNICAL DATA

The MC74LCX652 is a high performance, non–inverting octal

transceiver/registered transceiver operating from a 2.7 to 3.6V supply.

High impedance TTL compatible inputs significantly reduce current

loading to input drivers while TTL compatible outputs offer improved

REGISTERED TRANSCEIVER

switching noise performance. A V specification of 5.5V allows

MC74LCX652 inputs to be safely driven from 5V devices. The

MC74LCX652 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. Two Output

Enable pins (OEBA, OEAB) 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 (SBA, SAB) 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).
