... Octal Bidirectional Transceiver with TRI-STATE Inputs/Outputs General Description The ’AC/’ACT245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications. Current sinking capability both the A and B ports. The Transmit/Receive (T/R) input determines the direction of data flow through the bidi- rectional transceiver. Transmit (active-HIGH) enables data from A ports to B ports ...
