General Description
The ACQ/ACTQ245 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. The Output Enable input, when HIGH, disables both A and B ports by placing them in a HIGH Z condition. The ACQ/ACTQ utilizes Fairchild Quiet Series technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series features GTO output control and undershoot corrector in addition to a split ground bus for superior performance.
dynamic threshold performance Guaranteed pin-to-pin skew AC performance Improved latch-up immunity 3-STATE outputs drive bus lines or buffer memory address registers Outputs source/sink 24mA Faster prop delays than the standard ACT245
