Description
General Description
The AC/ACT245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended forbus-oriented applications. Current sinking capability is 24mA 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 (activeLOW) 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.
