Features

Description

• Four Operating Modes

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 right are accomplished

synchronously on the positive clock edge with serial data

entered at the shift left (DSL) serial input for the shift left

mode, and at the shift right (DSR) serial input for the shift

- Shift Right, Shift Left, Hold and Reset
