MC14194B - 4-Bit Bidirectional Universal Shift Register
MOTOROLA SEMICONDUCTOR TECHNICAL DATA 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.
