1 / 9 page © 2000 Fairchild Semiconductor Corporation DS010685 www.fairchildsemi.com March 1990 Revised September 2000 74ACQ544 • 74ACTQ544 Quiet Series Octal Registered Transceiver with 3-STATE Outputs General Description The ACQ/ACTQ544 is an inverting octal transceiver con- taining two sets of D-type registers for temporary storage of data flowing in either direction. Separate Latch Enable and Output Enable inputs are provided for each register to per- mit independent input and output control in either direction of data flow. The 544 inverts data in both directions. The ACQ/ACTQ utilizes Fairchild FACT Quiet Series technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO output control and undershoot cor- rector in addition to a split ground bus for superior perfor- mance. Features s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s 8-bit inverting octal latched transceiver s Separate controls for data flow in each direction s Back-to-back registers for storage s Outputs source/sink 24 mA Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Connection Diagram Pin Descriptions FACT , Quiet Series, FACT Quiet Series and GTO are trademarks of Fairchild Semiconductor Corporation.
