Single OR gate with Schmitt trigger for noise-immune logic
The SN74AUP1T32DCKR: The Schmitt-trigger action on both inputs provides hysteresis, cleaning up slow or noisy edges before they reach the gate — useful when the input signal comes from a mechanical switch, a long PCB trace, or a sensor with a slow rise time.
Propagation delay and drive capability
Maximum propagation delay is 4.4 ns at 3.3 V with a 30 pF load, so the gate switches fast enough for most control and interface applications without the power penalty of a higher-speed family. Output drive is symmetric at 4 mA source and 4 mA sink, enough to drive a downstream CMOS input or a low-power LED indicator.
Surface-mount mounting is the only option; no through-hole variant exists.
