8-Input Universal Shift/Storage Register

www.DataSheet4U.com 54ACC299 • 54ACT299 8-Input Universal Shift/Storage Register with Common Parallel I/O Pins September 1998 54AC299 • 54ACT299 8-Input Universal Shift/Storage Register with Common Parallel I/O Pins General Description The ’AC/’ACT299 is an 8-bit universal shift/storage register with TRI-STATE ® outputs. Four modes of operation are possible: hold (store), shift left, shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Additional outputs are provided for flip-flops Q0, Q7 to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register. n Common parallel I/O for reduced pin count n Additional serial inputs and outputs for expansion n Four operating modes: shift left, shift right, load and store n TRI-STATE outputs for bus-oriented applications n Outputs source/sink 24 mA n ’ACT299 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) ’AC299: 5962-88754 ’ACT299: 5962-88771 Features n ICC and IOZ reduced by 50% Ordering Code: Logic Symbols Connection Diagrams Pin Assignment for DIP and Flatpak DS100252-1 IEEE/IEC DS100252-2 Pin Assignment for LCC DS100252-3 DS100252-4 TRI-STATE ® is a registered trademark of National Semiconductor Corporation.
