Product details

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.

Frequently asked questions

Where can I buy SN74AUP1T32DCKR and how do I get a price?

The SN74AUP1T32DCKR is sourced through independent and authorized distribution channels.

Will SN74AUP1T32DCKR drop into a board specified around SN74LVC2G132DCUR without rewiring?

No — the SN74LVC2G132DCUR is a dual 2-input NAND gate in a different package (US8), while the SN74AUP1T32DCKR is a single OR gate in SC-70-5. The function, pinout, and footprint are not compatible without a board spin.
