OCTAL BIDIRECTIONAL  
TRANSCEIVER WITH 3-STATE  
INPUTS/OUTPUTS  
The MC54/74F245 contains eight noninverting bidirectional buffers with  
3-state outputs and is intended for bus-oriented applications. Current sinking  
capability is 24 mA at the A ports and 64 mA at the B ports. The Transmit/Re-  
ceive(T/R)inputdeterminesthedirectionofdataflowthroughthebidirectional  
transceiver. Transmit (active HIGH) enables data from A ports to B ports; Re-  
ceive (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.
