It integrates four independent NOR gates, each with two inputs. Supply range runs from 2 V to 6 V. Quiescent current is 2 µA maximum. The 15 ns propagation delay at 6 V and 50 pF load is typical for 74HC at this supply. The 5.2 mA output drive is symmetric high and low. Input logic thresholds are CMOS-compatible: low at 0.5 V to 1.8 V, high at 1.5 V to 4.2 V.","metaTitle":"MM74HC02J 74HC Quad 2-Input NOR Gate, 14-CDIP, Active","metaDescription":"Fairchild 74HC series quad 2-input NOR gate in hermetic 14-CDIP.

Each of the four gates has its inputs on pins 1-2, 4-5, 9-10, and 12-13, with outputs on pins 3, 6, 8, and 11 respectively.
