MC74AC245, MC74ACT245  
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.
