Shift Registers FAQ

How does the Schmitt-trigger input benefit signal integrity?

The Schmitt-trigger inputs provide hysteresis, making the device extremely tolerant to slow or noisy input signals and eliminating erroneous data outputs.

What is the function of the separate clocks?

Separate clocks are provided for the shift register (SRCLK) and the storage register (RCLK), allowing independent control over data shifting and output latching.
