Octal Bidirectional Transceiver With TRI- State
Inputs/Outputs
General Description
The AC245 contains eight non-inverting bidirectional buffers with 3-state outputs and is
intended for bus-oriented applications. Current sinking capability is 24 mA at the A and
B ports. The Transmit/Receiver (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.
