The MC74LCX2952 is a high performance, non–inverting octal
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 MC74LCX2952 inputs to
be safely driven from 5V devices. The MC74LCX2952 is suitable for
memory address driving and all TTL level bus oriented transceiver
applications.
Two 8–bit back to back registers store data from either of two
bidirectional buses. Data applied to the inputs is entered and stored on
the rising edge of the Clock (CAB, CBA) provided that the Clock Enable
(CEAB, CEBA) is Low. The data is then presented at the 3–state output
buffers, but is only accessible when the Output Enable (OEAB, OEBA) is
Low. The operation of the MC74LCX2952 is symmetrical — A inputs to B
outputs occurs in the same manner as B inputs to A outputs.
