Flip Flops FAQ

Does the SN74HCS574DGSR include reset functionality?

No, the SN74HCS574DGSR does not include a dedicated reset input. Data latching is controlled solely by the clock and output enable signals.

What is the purpose of the Schmitt-trigger inputs?

The Schmitt-trigger inputs provide hysteresis, which filters out noise and allows the device to correctly process slowly changing or noisy input signals without false triggering.
