Product details

Quad 2-input NOR gate in the 74HC family

The Texas Instruments SN74HC02DT is a quad 2-input NOR gate from the 74HC logic family, packaged in a 14-SOIC (3.90 mm width) surface-mount package. It operates across a 2V to 6V supply range and is rated for -40°C to 85°C. Each gate sinks or sources 5.2 mA, quiescent current is 2 µA, and propagation delay is 15 ns at 6V with 50 pF load.

Package and ordering code

The DT suffix in SN74HC02DT specifies the Tape & Reel (TR) and Cut Tape (CT) packaging options for the 14-SOIC body. The supplier device package is 14-SOIC, a common footprint that matches many existing PCB layouts. If your pick-and-place line runs tape-fed, the TR variant is the one to order.

Lifecycle and sourcing posture

The SN74HC02DT carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

Is SN74HC02DT obsolete?

No, the SN74HC02DT is Active in production with no discontinuation notice. It remains a current product in the 74HC series.

What are the alternatives to SN74HC02DT?

For a functionally similar quad 2-input gate, the SN74LV08ADR (AND gate) and SN74LV00APWR (NAND gate) are in the 74LV series with faster propagation delay (7.9 ns and 7.5 ns at 5V/50pF respectively) and a wider temperature range of -40°C to 125°C for the 08ADR. Both are surface-mount and operate at 2V to 5.5V. If you need a single-gate NOR, the SN74AHC1G00DBVT is a single 2-input NAND in SOT-23.

Does SN74HC02DT come in tape and reel?

Yes, the DT suffix indicates Tape & Reel (TR) and Cut Tape (CT) packaging options for the 14-SOIC package.
