74ACTQ843 Quiet Series™ 9-Bit Transparent Latch with 3-STATE Outputs March 1990 Revised December 1998 74ACTQ843 Quiet Series™ 9-Bit Transparent Latch with 3-STATE Outputs General Description The ACTQ843 bus interface latch is designed to eliminate the extra packages required to buffer existing latches and provide extra data width for wider address/data paths. The ACTQ843 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 corrector in addition to a split ground bus for superior performance. Features s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s Inputs and outputs on opposite sides of package for easy interface with microprocessors s Improved latch-up immunity s Outputs source/sink 24 mA s ACTQ843 has TTL-compatible inputs s Functionally and pin-compatible to AMD’s AM29843 s 3-STATE outputs for bus interfacing Ordering Code: Order Number 74ACTQ843SC 74ACTQ843SPC Package Number M24B N24C Package Description 24-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300” Wide Body 24-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-100, 0.300” Wide Device also available in Tape and Reel.
