SN74LS00N, Quad 2-Input NAND Gate Logic IC 5V - 14-Pin PDIP

The SN74LS00N is a TTL logic IC that contains four independent 2-input NAND gates in one 14-pin package. Each gate performs the NAND logic function, meaning the output goes LOW only when both inputs are HIGH. Texas Instruments describes the SN74LS00 family as 4-channel, 2-input, 4.75V to 5.25V bipolar NAND gates, making it suitable for standard 5V TTL digital logic circuits.

This IC is commonly used in digital electronics, logic control circuits, signal conditioning, pulse generation, clock logic, combinational logic circuits, microcontroller interfacing, and educational electronics projects. The PDIP through-hole package makes it easy to use on breadboards, stripboards, and through-hole PCBs.

The SN74LS00N is useful when a circuit requires basic NAND logic operations, and NAND gates are also widely used as universal logic gates because they can be combined to create other logic functions such as NOT, AND, OR, and NOR. Texas Instruments confirms that the SNx4xx00 devices contain four independent 2-input NAND gates and perform the positive-logic NAND function.
