SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX245 is a high performance, non–inverting octal  
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  
LOW–VOLTAGE CMOS  
OCTAL TRANSCEIVER  
performance. A V specification of 5.5V allows MC74LCX245 inputs to be  
I
safely driven from 5V devices. The MC74LCX245 is suitable for memory  
address driving and all TTL level bus oriented transceiver applications.  
Current drive capability is 24mA at both A and B ports. The  
Transmit/Receive (T/R) input determines the direction of data flow  
through the bi–directional transceiver. Transmit (active–HIGH) enables  
data from A ports to B ports; Receive (active–LOW) enables data from B  
to A ports. The Output Enable input, when HIGH, disables both A and B  
ports by placing them in a HIGH Z condition.
