MC74LCX2952

The MC74LCX2952 is a high performance, noninverting 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 8bit 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 3state 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.
