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 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.

The LS95B is fabricated with the Schottky barrier diode process for high speed and is completely compatible with all Motorola TTL families.
