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 Features The ACQ/ACTQ245 contains eight non-inverting bidirec-I and I reduced by 50% CC OZ tional buffers with 3-STATE outputs and is intended for bus- Guaranteed simultaneous switching noise level and oriented applications. Current sinking capability is 24 mA at dynamic threshold performance both the A and B ports. The Transmit/Receive (T/R) input Guaranteed pin-to-pin skew AC performance determines the direction of data flow through the bidirec- Improved latch-up immunity tional transceiver. Transmit (active-HIGH) enables data from A Ports to B Ports; Receive (active-LOW) enables3-STATE outputs drive bus lines or buffer memory data from B Ports to A Ports. The Output Enable input, address registers when HIGH, disables both A and B ports by placing them in Outputs source/sink 24 mA a HIGH Z condition. Faster prop delays than the standard ACT245 The ACQ/ACTQ utilizes Fairchild Quiet Series technol- ogy to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series fea- tures GTO output control and undershoot corrector in addition to a split ground bus for superior performance.
