Part Details:

74A CQ245, January 2008 74A 74ACQ245, 74ACTQ245 CTQ245 -- Quiet SeriesTM Octal Bidirectional Quiet SeriesTM Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs Features General Description ICC and IOZ reduced by 50% The ACQ/ACTQ245 contains eight non-inverting bidirec- Guaranteed simultaneous switching noise level and tional buffers with 3-STATE outputs and is intended for dynamic threshold performance bus-oriented applications. Current sinking capability is Guaranteed pin-to-pin skew AC performance 24mA at both the A and B ports. The Transmit/Receive(T/R) input determines the direction of data flow through Improved latch-up immunity the bidirectional transceiver. Transmit (active-HIGH) 3-STATE outputs drive bus lines or buffer memory enables data from A Ports to B Ports; Receive (active- address registers LOW) enables data from B Ports to A Ports. The Output Outputs source/sink 24mA Enable input, when HIGH, disables both A and B ports Faster prop delays than the standard ACT245 by placing them in a HIGH Z condition. The ACQ/ACTQ utilizes Fairchild Quiet SeriesTMtechnology to guarantee quiet output switching andimprove dynamic threshold performance. FACT QuietSeriesTM features GTOTM output control and undershootcorrector in addition to a split ground bus for superiorperformance.
