It integrates four independent NOR gates in a single 14-pin DIP package (14-PDIP, 0.300\" body width) for through-hole mounting. Each gate accepts two inputs and delivers a NOR output with TTL-compatible levels. The 74LS series balances speed and power, with a typical propagation delay of 15 ns at 5 V and 15 pF load, making it suitable for general-purpose logic in commercial-temperature (0°C to 70°C) environments such as industrial control panels, office equipment, and consumer electronics. ## Supply and drive — what the ratings mean for the BOM The SN74LS02N operates from a 4.75 V to 5.25 V supply. Input low threshold is 0.8 V; input high threshold is 2 V. ## Lifecycle and sourcing No end-of-life notice or last-time-buy schedule is in effect.","metaTitle":"SN74LS02N 74LS Quad 2-Input NOR Gate, 15 ns @ 5 V","metaDescription":"TI SN74LS02N quad 2-input NOR gate in 14-DIP, 4.75-5.25 V supply, 15 ns propagation delay.
