SEMICONDUCTOR TECHNICAL DATA  
LOW–VOLTAGE CMOS  
OCTAL REGISTERED  
TRANSCEIVER  
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 V specification of 5.5V allows MC74LCX2952 inputs to  
I
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.
