74ACQ245 74ACTQ245 Quiet Series Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs July 1989 Revised November 1999 74ACQ245 74ACTQ245 Quiet Series Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs General Description The ACQ/ACTQ245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for busoriented 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. 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. Features s ICC and IOZ reduced by 50% s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s Improved latch-up immunity s 3-STATE outputs drive bus lines or buffer memory address registers s Outputs source/sink 24 mA s Faster prop delays than the standard ACT245 Ordering Code: Order Number 74ACQ245SC 74ACQ245SJ 74ACQ245PC 74ACTQ245SC 74ACTQ245SJ 74ACTQ245QSC 74ACTQ245MSA 74ACTQ24...
