FAQ

How do the set and reset inputs function relative to the clock?

The set and reset inputs are asynchronous and active-low, meaning they operate independently of the clock input to immediately force the output states.

What is the purpose of the Schmitt trigger action on the inputs?

Schmitt trigger action makes the circuit highly tolerant of slower input rise and fall times, improving noise immunity in signal paths.
