SN54/74LS95B 4-BIT SHIFT REGISTER The SN54/74LS95B is a 4-Bit Shift Register with serial and parallel synchronous operating modes. The serial shift right and parallel load are acti- vated 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 4-BIT SHIFT REGISTER synchronous with the HIGH to LOW transition of the appropriate clock input. The LS95B is fabricated with the Schottky barrier diode process for high LOW POWER SCHOTTKY speed and is completely compatible with all Motorola TTL families. • Synchronous, Expandable Shift Right • Synchronous Shift Left Capability • Synchronous Parallel Load • Separate Shift and Load Clock Inputs J SUFFIX • Input Clamp Diodes Limit High Speed Termi
