FAQ

What is the function of the reset input?

The reset input is asynchronous and active-low. When asserted low, it forces all Q outputs to a low state regardless of the clock or D input states.

How many independent clocks does the device support?

The device supports two independent clock inputs, each controlling a pair of flip-flops within the octal configuration.
