54ACT245 - Octal Bidirectional Transceiver

Download the 54ACT245 datasheet PDF. This datasheet also covers the 54AC245 variant, as both devices belong to the same octal bidirectional transceiver family and are provided as variant models within a single manufacturer datasheet.

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 is 24 mA at both the A and B ports.

Current sinking capability is 24 mA 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.
