Features  
Description  
• Four Operating Modes  
The ’HC194 and CD74HCT194 are 4-bit shift registers with  
Asynchronous Master Reset (MR). In the parallel mode (S0  
and S1 are high), data is loaded into the associated flip-flop  
and appears at the output after the positive transition of the  
clock input (CP). During parallel loading serial data flow is  
inhibited. Shift left and shift right are accomplished  
synchronously on the positive clock edge with serial data  
entered at the shift left (DSL) serial input for the shift right  
mode, and at the shift right (DSR) serial input for the shift left  
- Shift Right, Shift Left, Hold and Reset
