Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at these or any other conditions above those indicated in the operational sec-

tions of this specifi cation is not implied. Exposure to absolute maximum rating conditions for external periods may affect device

reliability.

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.
