54ACQ245 - Quiet Series Octal Bidirectional Transceiver

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.

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.
