Product details

It operates from a 4.5 V to 5.5 V supply and is rated from -40°C to 85°C.

9 ns propagation delay — timing budget for a 5 V bus

With a maximum propagation delay of 9 ns at 5 V into a 50 pF load, the SN74AHCT132D is fast enough to sit between a 50 MHz microcontroller and a peripheral without adding a full clock cycle of latency. The 8 mA output drive is enough to switch a handful of CMOS inputs or a short ribbon cable, but if you're driving a long trace or a high fan-out, you'll want to buffer it. The quiescent current maxes out at 2 µA, so it won't eat into your standby budget.

Active and RoHS3 — no supply-chain surprises

There's no end-of-life notice, no last-time-buy pressure, and no lead-free exemption to track. It's a standard catalog part that you can qualify into a production BOM without worrying about a sudden discontinuation.

14-SOIC footprint — board-level fit

Housed in a 14-SOIC package (0.154" body width, 3.90 mm) with a surface-mount footprint, this part is a drop-in for any standard SOIC-14 land pattern.

Frequently asked questions

What is the difference between SN74AHCT132D and SN74HC132D?

Both are quad 2-input NAND gates with Schmitt-trigger inputs, but the AHCT family is optimized for TTL-compatible input thresholds and operates at 4.5 V to 5.5 V, while the HC family uses CMOS thresholds over a wider 2 V to 6 V range. The AHCT variant is a direct drop-in if your system already runs on a 5 V rail and you want the tighter switching points of TTL logic.

Does SN74AHCT132D have Schmitt-trigger inputs?

Yes, the device features Schmitt-trigger inputs on all four gates. This gives hysteresis on the input thresholds, so the gate will clean up a noisy or slow-rising signal and won't oscillate near the switching point.

What is the closest functional second-source for SN74AHCT132D?

The SN74AHC1G00DBVT is a single-gate NAND from the same TI family, but it is a single circuit in a smaller SOT-23 package and lacks the Schmitt-trigger feature. For a direct quad replacement with Schmitt-trigger inputs, stick with the SN74AHCT132D or its HC counterpart.
