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
switching noise performance. A VI 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).
