Product details

Quiescent current and output drive

The SN74AHCT1G32DCKT: Quiescent supply current is 1 µA maximum, negligible for battery-powered or always-on circuits. Each output can source or sink 8 mA — enough to drive a single LED, a small relay coil through a transistor, or the input of a downstream logic gate without buffering.

Packaging and sourcing

The SN74AHCT1G32DCKT is an active, in-production part. It ships on Tape & Reel (TR) or Cut Tape (CT). For a BOM line that needs this exact logic gate, we source and quote to order against an RFQ.

Frequently asked questions

Is SN74AHCT1G32DCKT RoHS compliant?

Yes, it is ROHS3 compliant.

What is the closest functional equivalent for SN74AHCT1G32DCKT?

The SN74AHCT1G02DCKR is a pin-compatible 2-input NOR gate in the same 74AHCT series and SC-70-5 package. It is not a direct OR-gate substitute but shares the same footprint and supply characteristics for designs that can invert the logic function.
