Technical Details & Description

Quad 2-input NAND gate in a 14-pin DIP

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.

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.

Frequently asked questions

What is the function of SN7400N?

The SN7400N is a quad 2-input NAND gate. 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.

What is the difference between SN7400N and SN74LS00N?

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).

What are the equivalents or replacements for SN7400N?

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.
