COMPLETE DATA SHEET COMING SOON! 4-Bit Bidirectional Universal Shift Register
Description
CD54HC194/3A CD54HCT194/3A 4-bit shift registers with Asynchronous Master Reset (MR). parallel mode high), data loaded into associated flip-flop appear output after positive transition clock input (CP). During parallel loading, serial data flow inhibited. Shift left shift right accomplished synchronously positive clock edge with serial data entered shift left (DSL) serial input shift-right mode, shift right (DSR) serial input shift-left mode. Clearing register accomplished applied Master Reset (MR) pin.
