Quad 2-input NAND gate in a 14-pin DIP
The Texas Instruments SN7400N is a quad 2-input NAND gate from the industry-standard 7400 series of TTL logic devices. 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.
