... Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs General Description The AC/ACT245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus-ori- ented applications. Current sinking capability both the A and B ports. The Transmit/Receive (T/R) input determines the direction of data flow through the bidirec- tional transceiver. Transmit (active-HIGH) enables data from A ports to B ports ...
