Product details

Device identity and board-fit

The SN74HCT02N is a quad 2-input NOR gate from the 74HCT logic family, in a 14-pin DIP package (0.300" body width) for through-hole mounting.

Parametric profile for the BOM

Four independent NOR gates, each with two inputs, in one 14-DIP package — consolidates board space versus using multiple single-gate packages. Quiescent current is 2 µA maximum, keeping the static power draw negligible in battery-backed or always-on logic sections. Output drive capability is 4 mA source and 4 mA sink, sufficient for driving standard CMOS inputs or a single TTL load per output.

Lifecycle and compliance

ROHS3 compliant, so it fits lead-free assembly processes without exemption paperwork.

Frequently asked questions

Is SN74HCT02N active or obsolete?

The SN74HCT02N is active — Texas Instruments lists it as current production with no discontinuation notice.

How does SN74HCT02N compare to SN74HC02N?

Both are quad 2-input NOR gates in the same pinout and package. The HCT version (SN74HCT02N) has TTL-compatible input thresholds, while the HC version uses CMOS thresholds. If the driving device outputs TTL levels, the HCT variant is the correct fit.
