Shift Registers FAQ

How are the dual serial inputs handled?

The two serial data inputs (DSA and DSB) perform a logical AND operation. They can be connected together or one can be tied high to enable the other.

What triggers the data shift?

Data shifts on the rising edge of the clock pulse (CP).
