SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX16245 is a high performance, non–inverting 16–bit  
transceiver operating from a 2.7 to 3.6V supply. The device is byte  
controlled. Each byte has separate Output Enable inputs which can be  
tied together for full 16–bit operation. High impedance TTL compatible  
inputs significantly reduce current loading to input drivers while TTL  
LOW–VOLTAGE  
compatible outputs offer improved switching noise performance. A V

specification of 5.5V allows MC74LCX16245 inputs to be safely driven  
from 5V devices. The MC74LCX16245 is suitable for memory address  
driving and all TTL level bus oriented transceiver applications.  
4.5ns maximum propagation delays support high performance  
applications. Current drive capability is 24mA at both A and B ports. The  
Transmit/Receive (T/Rn) inputs determine 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 inputs (OEn), when HIGH, disable both A  
and B ports by placing them in a HIGH Z condition.
