SN74LS299
8−Bit Shift/Storage Register with 3−State Outputs
The SN74LS299 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.
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
