FAST AND LS TTL DATA
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
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.
Synchronous, Expandable Shift Right
Synchronous Shift Left Capability
Synchronous Parallel Load
Separate Shift and Load Clock Inputs
Input Clamp Diodes Limit High Speed Termination Effects
NOTE:
The Flatpak version has the
same pinouts (Connection
Diagram) as the Dual In-Line
Package.
