It integrates four independent NAND gates, each with two inputs, in a single 14-pin plastic DIP package (14-DIP, 0.300\" body width). The part operates from a nominal 5 V supply rail (4.75 V to 5.25 V) and is specified over the commercial temperature range of 0°C to 70°C, making it suitable for benchtop instrumentation, office equipment, and general-purpose digital logic in indoor environments where controlled temperature is expected. ## 22 ns propagation delay — timing margin for non-critical paths The maximum propagation delay is 22 ns at 5 V with a 15 pF load. ## Output drive: 400 µA sourcing, 16 mA sinking Each output can source 400 µA (logic high) and sink 16 mA (logic low). ## Through-hole 14-DIP — legacy board compatibility The 14-DIP (0.300\" row spacing) with through-hole mounting is the original dual-inline package format. ## Active lifecycle — no end-of-life risk for new designs The SN7400N carries an Active product status per Texas Instruments, with ROHS3 compliance.","metaTitle":"SN7400N Quad 2-Input NAND Gate, 14-DIP, 22 ns","metaDescription":"TI SN7400N quad 2-input NAND gate, 4.75-5.25 V supply, 22 ns propagation delay, 14-DIP through-hole.

It contains four independent NAND gates, each with two inputs, in a single 14-pin DIP package. The output is the logical NAND of the two inputs."},{"question":"What is the difference between SN7400N and SN74LS00N?","answer":"The SN74LS00N is the low-power Schottky variant of the same quad 2-input NAND gate. It operates from the same 5 V supply but offers lower power consumption (about 2 mW per gate vs 10 mW for the standard 7400), higher output drive (8 mA sink vs 16 mA), and faster propagation delay (15 ns typical vs 22 ns max). The pinout and function are identical, so the LS00N is a drop-in replacement where lower power is needed, though the input thresholds differ slightly (0.8 V low, 2.0 V high for both)."},{"question":"What are the equivalents or replacements for SN7400N?","answer":"Pin-compatible equivalents in the same 14-DIP footprint include the SN74LS00N (low-power Schottky), SN74S00N (Schottky, faster), and SN74HC00N (high-speed CMOS, wider supply range). All share the same quad 2-input NAND function and 14-DIP package. Verify supply voltage and logic-level compatibility before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN7400N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN7400N when reusing this data.
