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. 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%
■ Guaranteed simultaneous switching noise level and dynamic threshold performance
■ Improved latch-up immunity
■ TRI-STATE outputs drive bus lines or buffer memory address registers
■ Outputs source/sink 24 mA
■ Faster prop delays than the standard ’ACT245
■ 4 kV minimum ESD immunity (’ACQ)
■ Standard Military Drawing (SMD)
    — ’ACTQ245: 5962-92187
    — ’ACQ245: 5962-92177
