MC74F299 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.
