54AC245 54ACT245 Octal Bidirectional Transceiver with TRI-STATE Inputs/Outputs
54AC245 54ACT245 Octal Bidirectional Transceiver with TRI-STATE � Inputs/Outputs

The 'AC/'ACT245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications. Current sinking capability 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.

Features

ICC and IOZ reduced by 50% Noninverting buffers Bidirectional data path A and B outputs source/sink mA 'ACT245 has TTL-compatible inputs Standard Microcircuit Drawing (SMD) 'ACT245: 5962-87663

Description Output Enable Input Transmit/Receive Input Side A TRI-STATE Inputs or TRI-STATE Outputs Side B TRI-STATE Inputs or TRI-STATE Outputs

Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. National does not recommend operation of FACT � circuits outside databook specifications.
