Octal Bidirectional Transceiver with 3-STATE  
Inputs/Outputs  
Features  
General Description  
I and I reduced by 50%  
The AC/ACT245 contains eight non-inverting bidirec-  
tional buffers with 3-STATE outputs and is intended for  
bus-oriented applications. Current sinking capability is  
24mA 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.
