Quad 2-input NOR gate in 14-DIP
The SN74AHCT02N is a quad 2-input NOR gate from Texas Instruments' 74AHCT series, packaged in a 14-lead DIP (0.300" body width) for through-hole assembly. Each of the four gates sinks or sources 8 mA at the output, sufficient for driving standard TTL loads or LED indicators through a current-limiting resistor. The 7.5 ns propagation delay at 5 V and 50 pF load keeps the gate fast enough for 5 V logic systems running at moderate clock rates.
Quiescent current is 2 µA max, so the gate adds negligible standby draw in battery-backed or always-on logic sections.
