HCF40194B

HCF40194B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP packages. HCF40194B 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 output after the positive transition of the CLOCK input. During loading, serial data flow is inhibited. Shift right and shift left are synchronously accomplished 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. HCF40194B is similar to industry types 340194 and MC40194.
