Each of the four independent gates performs the NOR function on two inputs, with a propagation delay of 15 ns at 5V and 15 pF load. Output drive is rated at 400 µA sourcing and 16 mA sinking. ## Active production, ROHS3 compliant No last-time-buy or end-of-life notice is on record. For a BOM freeze or a long-production-run line, this part is a safe choice.","metaTitle":"SN74LS02DR Texas Instruments NOR Gate, 74LS Series, 14-SOIC","metaDescription":"SN74LS02DR quad 2-input NOR gate from TI's 74LS series. 15 ns propagation delay at 5V, 15pF. 4.75V to 5.25V supply. 0°C to 70°C.
