74F299
Octal Universal Shift/Storage Register
with Common Parallel I/O Pins
General Description
The 74F299 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. Additional outputs, Q
