That speed comes with asymmetric output drive: 1 mA source (logic high) versus 20 mA sink (logic low). The low-side drive handles standard TTL fan-out of 10 loads, but the high-side is limited — the gate cannot drive a heavily loaded bus line high without external pull-up or a buffer. ## Supply rails and temperature grade Runs on a single 5V rail, 4.75V to 5.25V — strict 5V ±5% tolerance, no wide-VIN margin. The 0°C to 70°C commercial temperature range suits indoor equipment, bench instrumentation, and telecom line cards in conditioned environments. Input thresholds are 0.8V low and 2.0V high, compatible with standard 5V TTL and CMOS logic families that meet the same levels. The 14-SOIC (3.90 mm width) body is a common footprint shared with 74LS and 74HC quad gates — board layout swaps without a respin.","metaTitle":"SN74S02D 74S Quad NOR Gate, 5 ns @ 5V, 14-SOIC","metaDescription":"SN74S02D quad 2-input NOR gate from the 74S Schottky family. 5 ns propagation delay at 5V, 50pF. 4.75V–5.25V supply, 0°C–70°C.
