NTE4194B Integrated Circuit CMOS, 4Bit Bidirectional Universal Shift Register Description: The NTE4194B is a universal shift register in a 16Lead DIP type package featuring parallel inputs, parallel outputs SHIFT RIGHT and SHIFT LEFT serial inputs, an a direct overriding clear input. In the parallelload mode (S and S1 are high), dat is loaded into the associated flipflop and appears at the output after the positive traition 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 inhibited when both mode control inputs are low. When low, the RESET input resets all stages and forces all outputs low.
