Description  
The CD40104BMS is a universal shift register featuring parallel  
inputs, parallel outputs, SHIFT RIGHT and SHIFT LEFT serial  
inputs, and a high impedance third output state allowing the device  
to be used in bus organized systems.  
Functional Diagrams  
In the parallel load 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. During loading, serial data flow is  
inhibited. Shift right and shift left are accomplished synchronously  
on the positive clock edge with serial data entered at the SHIFT  
RIGHT and SHIFT LEFT serial inputs, respectively. Clearing the  
register is accomplished by setting both mode controls low and  
clocking the register. When the output enable input is low, all outputs  
assume the high impedance state.

The CD40194BMS is a universal shift register featuring parallel inputs,  
parallel outputs SHIFT RIGHT and SHIFT LEFT serial inputs, and a  
direct overriding clear input. In the parallel load mode (S0 and S1 are  
high), data is loaded into the associated flip-flop and appears at the out-  
put after the positive transition of the CLOCK input. During loading,  
serial data flow is inhibited. Shift right and shift left are accomplished  
synchronously on the positive clock edge with data entered at the  
SHIFT RIGHT and SHIFT LEFT serial inputs, respectively. Clocking of  
the register is inhibited when both mode control inputs are low. When  
low, the RESET input resets all stages and forces all outputs low. The  
CD40194BMS is similar to industry types 340194 and MC40194.
