74ACT245
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-oriented applications. 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.

Features

  • ICC and IOZ reduced by 50%
  • Non-inverting buffers
  • Bidirectional data path
  • A and B outputs source/sink 24 mA
  • ACT245 has TTL-compatible inputs
