8-INPUT UNIVERSAL
SHIFT/STORAGE REGISTER
WITH COMMON PARALLEL I/O PINS
The MC74F299 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
