Description
The ’HC194 and CD74HCT194 are 4-bit shift registers with
Asynchronous Master Reset (MR). In the parallel 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 (CP). During parallel loading serial data flow is
inhibited.
Shift
left
and
shift
synchronously on the positive clock edge with serial data
entered at the shift left (DSL) serial input for the shift right
mode, and at the shift right (DSR) serial input for the shift left
mode. Clearing the register is accomplished by a Low
applied to the Master Reset (MR) pin.
