1 / 8 page March 1990 Revised December 1998 © 1999 Fairchild Semiconductor Corporation DS010689.prf www.fairchildsemi.com 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 ™ technol- ogy to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series fea- tures 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: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
