MC74AC299, MC74ACT299  
8−Input Universal Shift/  
Storage Register with  
Common Parallel I/O Pins  
The MC74AC299/74ACT299 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 are provided for flip−flops Q , Q to

allow easy serial cascading. A separate active LOW Master Reset is  
used to reset the register.
