OCTAL BIDIRECTIONAL  
TRANSCEIVER  
WITH 3-STATE  
INPUTS/OUTPUTS  
The MC74AC245/74ACT245 contains eight non-inverting bidirectional buffers  
with 3-state outputs and is intended for bus-oriented applications. Current sinking  
capability is 24 mA at both the A and B ports. The Transmit/Receive (T/R) input  
determines the direction of data flow through the bidirectional transceiver. Transmit  
(active-HIGH) enables data from A ports to B ports; Receive (active-LOW) enables  
data from B ports to A ports. The Output Enable input, when HIGH, disables both A  
and B ports by placing them in a High Z condition.
