HCC40104B Datasheet, PDF (2/12 Pages) STMicroelectronics – 4-BIT BIDIRECTIONAL UNIVERSAL SHIFT REGISTER

HCC/HCF40104B/40194B
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 data
entered at the SHIFT RIGHT and SHIFT LEFT serial

inputs, respectively. Clocking of the register is in-
hibited when both mode control inputs are low. When
low, the RESET input resets all stages and forces all
outputs low. The HCC/HCF40194B is similar to in-
dustry types 340194 and MC40194.
