4-Bit Bidirectional Universal Shift Register

Features

Description

• Four Operating Modes

The Harris CD74HC194 and CD74HCT194 are 4-bit shift

registers with Asynchronous Master Reset (MR). In the par-

allel mode (S0 and S1 are high), data is loaded into the

associated ﬂip-ﬂop and appears at the output after the posi-

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

- Shift Right, Shift Left, Hold and Reset

• Synchronous Parallel or Serial Operation
