DM74LS95B Datasheet | National Semiconductor

Description The ’LS95B is a 4-bit shift register with serial and parallel synchronous operating modes The serial shift right and parallel load are activated by separate clock inputs which are selected by a mode control input The data is transferred from the serial or parallel D inputs to the Q outputs synchronous with the HIGH-to-LOW transition of the appropriate clock input Features Synchronous expandable shift right Synchronous shift left capability Synchronous parallel load Separate shift and load clock inputs Connection Diagram Logic Symbol Dual-In-Line Package TL F 10175- 2 TL F 10175- 1 VCC e Pin 14 GND e Pin 7 Order Number DM54LS95BJ DM54LS95BN DM74LS95BM or DM74LS95BN See NS Package Number J14A M14A N14A or W14B Pin Names CP1 CP2 DS P0- P3 PE Q0- Q3 Description Serial Clock Input (Active Falling Edge) Parallel Clock Input (Active Falling Edge) Serial Data Input Parallel Data Inputs Parallel Enable Input (Active HIGH) Parallel Outputs C1995 National Semiconductor Corporation TL F 10175 RRD-B30M105 Printed in U S A .. .. ..
