Quiet Series⢠Octal Bidirectional Transceiver with
3-STATE Inputs/Outputs
Features
â ICC and IOZ reduced by 50%
â Guaranteed simultaneous switching noise level and
dynamic threshold performance
â Guaranteed pin-to-pin skew AC performance
â Improved latch-up immunity
â 3-STATE outputs drive bus lines or buffer memory
address registers
â Outputs source/sink 24mA
â Faster prop delays than the standard ACT245
General Description
The ACQ/ACTQ245 contains eight non-inverting bidirec-
tional 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 (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.
The ACQ/ACTQ utilizes Fairchild Quiet Seriesâ¢
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.
