4-Bit Bidirectional Universal Shift Register  
Features  
Description  
• Four Operating Modes  
The Harris CD74HC194 and CD74HCT194 are 4-bit shift  
registers with Asynchronous Master Reset (MR). In the par-  
allel mode (S0 and S1 are high), data is loaded into the  
associated flip-flop and appears at the output after the posi-  
tive 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  
- Shift Right, Shift Left, Hold and Reset
