8−Input Universal Shift/

Storage Register with

Common Parallel I/O Pins

The MC74AC299/74ACT299 is an 8−bit universal shift/storage

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 , Q to

allow easy serial cascading. A separate active LOW Master Reset is

used to reset the register.
