MC74AC299, MC74ACT299
8−Input Universal Shift/
Storage Register with
Common Parallel I/O Pins
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 are provided for flip−flops Q
allow easy serial cascading. A separate active LOW Master Reset is
used to reset the register.
