1 / 10 page 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 pos- sible: hold (store), shift left, shift right and load data. The par- allel load inputs and flip-flop outputs are multiplexed to re- duce the total number of package pins. Additional outputs are provided for flip-flops Q 0,Q7 to allow easy serial cascad- ing. A separate active LOW Master Reset is used to reset the register. Features n ICC and IOZ reduced by 50% 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 Ordering Code: Logic Symbols Connection Diagrams TRI-STATE® is a registered trademark of National Semiconductor Corporation.
