Shift Registers FAQ

How does the asynchronous reset function operate?

A LOW signal on the RESET (CLR) pin immediately resets the shift register, forcing all outputs to the LOW state regardless of the current input conditions or clock signals.

What is the maximum clock frequency for this device?

The typical maximum clock frequency (fMAX) is 60 MHz at a supply voltage of 5 V, a load capacitance of 15 pF, and an ambient temperature of 25°C.
