Each gate performs the NOR function on five inputs, producing a low output only when all inputs are high — useful for wide-address decoding, glitch-free OR-ing, or compact logic trees where board space is tight. The 74S Schottky family delivers a propagation delay of 6 ns at 5 V driving a 15 pF load, making it one of the faster NOR options for 5 V logic systems. ## Supply rail and temperature — 5 V only, indoor environments This part operates from a 4.75 V to 5.25 V supply — strictly a 5 V rail part. The input thresholds are fixed for TTL-compatible 5 V logic. ## Output drive and loading — 1 mA high, 20 mA low The output current capability is asymmetric: 1 mA sourcing (logic high) and 20 mA sinking (logic low). This is typical for Schottky TTL and means the gate can drive a few standard TTL inputs or a low-power LED, but not a heavy load. The 6 ns propagation delay is specified at 5 V with a 15 pF load — stay within that capacitance budget to maintain timing margin. ## Active lifecycle — no obsolescence concern for new builds The SN74S260D carries an Active product status and is RoHS3 compliant. This is a current-production part suitable for both new designs and ongoing production, with no near-term obsolescence risk.","metaTitle":"SN74S260D NOR Gate, 2-Ch 5-Input, 14-SOIC, 6ns","metaDescription":"TI SN74S260D dual 5-input NOR gate in 14-SOIC. 6ns propagation delay at 5V, 15pF. 4.75V–5.25V supply, 0°C–70°C.
