4-Bit Bidirectional Universal Shift Register Features Description Four Operating Modes
-Shift Right, Shift Left, Hold and Reset Synchronous Parallel or Serial Operation Fanout (Over Temperature Range)
-Standard Outputs . 10 LSTTL Loads
-Bus Driver Outputs . 15 LSTTL Loads 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 …
