74ACT245 - Octal Bidirectional Transceiver

Download the 74ACT245 datasheet PDF. This datasheet also covers the 74AC245 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 3-STATE outputs and is intended for bus-oriented applications.

Current sinking capability is 24mA at both the A and B ports.

Key Features

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

74AC245, 74ACT245 — Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs January 2008 74AC245, 74ACT245 Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs Features ■ ICC and IOZ reduced by 50% ■ Non-inverting buffers ■ Bidirectional data path ■ A and B outputs source/sink 24mA ■ ACT245 has TTL-compatible 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 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.
