74AC245 Datasheet | Fairchild Semiconductor

Features - ICC and IOZ reduced by 50% - Non-inverting buffers - Bidirectional data path - A and B outputs source/sink 24m A - ACT245 has TTL-patible inputs General Description The AC/ACT245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus-oriented applications. Current sinking capability is 24m A 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.
