Product details

Single 2-input OR gate in a tiny SC-70-5

The TI SN74AHC1G32DCKT is a single 2-input OR gate from the 74AHC family, in a 5-pin SC-70-5 (SOT-353) surface-mount package. Supply range is 2V to 5.5V.

What the ratings mean for your BOM

The 8mA output drive (both source and sink) is standard for the AHC family — enough to drive three or four LSTTL loads or a handful of CMOS inputs, but not a relay coil or an LED without a buffer. If you need to fan out to a heavy load, plan a transistor or a gate buffer downstream. Quiescent current maxes out at 1 µA — essentially nothing for a battery-powered design. The gate draws almost no current when the outputs are static.

Temperature grade and environment

Rated for -40°C to 85°C, the industrial temperature range.

Frequently asked questions

What is the function of SN74AHC1G32DCKT?

It is a single 2-input OR gate. It outputs a logic high when either or both of its two inputs are high. Used for basic logic combining, signal gating, and glue logic in digital circuits.

Is SN74AHC1G32DCKT suitable for 3.3V logic?

Yes. The supply range is 2V to 5.5V, so it runs on 3.3V directly. Input thresholds scale with supply — at 3.3V the low threshold is about 0.9V and the high threshold about 2.0V, making it compatible with standard 3.3V CMOS and LVTTL outputs.

What is the difference between SN74AHC1G32DCKT and SN74AHC1G32DCKR?

The only difference is the packaging format. The DCKT suffix is Cut Tape (CT), while the DCKR suffix is Tape & Reel (TR). The silicon, the SC-70-5 package, and all electrical specs are identical.

What are the alternatives to SN74AHC1G32DCKT?

The SN74AHC1G00DBVT is a NAND gate in the same 74AHC family and same SC-70-5 footprint — same supply range, same speed, but inverts the logic. The SN74AHCT1G02DCKR is a NOR gate in the 74AHCT family (4.5V to 5.5V only). If you need a quad 2-input NAND, the SN74LV00APWR is a 74LV part in a TSSOP-14 with 12mA output drive.
