MC14194B
4-Bit Bidirectional Universal
Shift Register
The MC14194B is a 4–bit static shift register capable of operating in the
parallel load, serial shift left, serial shift right, or hold mode. The
asynchronous Reset input, when at a low level, overrides all other inputs,
resets all stages, and forces all outputs low. When Reset is at a logic 1 level,
the two mode control inputs, S0 and S1, control the operating mode as
shown in the truth table. Both serial and parallel operation are triggered on
the positive–going transition of the Clock input. The Parallel Data, Data Shift,
and mode control inputs must be stable for the specified setup and hold
times before and after the positive–going Clock transition.
• Synchronous Right/Left Serial Operation
• Synchronous Parallel Load
• Asynchronous Hold (Do Nothing) Mode
