SN54LS299
SN54/74LS299 8-BIT SHIFT/STORAGE REGISTER WITH 3-STATE OUTPUTS The SN54 / 74LS299 is an 8-Bit Universal Shift / Storage Register with 3-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. Separate outputs are provided for flip-flops Q0 and Q7 to allow easy cascading. A separate active LOW Master Reset is used to reset the register. 8-BIT SHIFT/STORAGE REGISTER WITH 3-STATE OUTPUTS LOW POWER SCHOTTKY • Common I/O for Reduced Pin Count • Four Operation Modes: Shift Left, Shift Right, Load and Store • Separate Shift Right Serial Input and Shift Left Serial Input for Easy Cascading • 3-State Outputs for Bus Oriented Applications • Input Clamp Diodes Limit High-Speed Termination Effects • ESD > 3500 Volts 20 1 J SUFFIX CERAMIC CASE 732-03 20 N SUFFIX PLASTIC CASE 738-03 1 CONNECTION DIAGRAM DIP (TOP VIEW) V CC 20 S 1 19 D s7 1.
