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. 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 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.

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.
