The output can source 400µA and sink 16mA, enough to drive standard TTL loads or a few CMOS inputs on the same 5V rail. Input logic thresholds are 0.8V low and 2V high, compatible with 5V TTL and 74LS family outputs.","metaTitle":"SN74LS02D Texas Instruments 74LS NOR Gate, 14-SOIC","metaDescription":"SN74LS02D quad 2-input NOR gate in 14-SOIC, 4.75V–5.25V supply, 15ns propagation delay at 5V.
