54ACTQ245 - Quiet Series Octal Bidirectional Transceiver

Download the 54ACTQ245 datasheet PDF. This datasheet also covers the 54ACQ245 variant, as both devices belong to the same quiet series octal bidirectional transceiver family and are provided as variant models within a single manufacturer datasheet.

General Description

The ’ACQ/’ACTQ245 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.

Key Features

  • GTO™ output control and undershoot corrector in addition to a split ground bus for superior performance. Features n ICC and IOZ reduced by 50% n Guaranteed simultaneous switching noise level and dynamic threshold performance n Improved latch-up immunity n TRI-STATE outputs drive bus lines or buffer memory address registers n Outputs source/sink 24 mA n Faster prop delays than the standard ’ACT245 n 4 kV minimum ESD immunity (’ACQ) n Standard Military Drawing (SMD).
  • ’ACTQ245: 5962-92187.

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.
