The 74LS00 is a digital integrated circuit by Texas Instruments containing four independent 2-Input NAND gates. Built with Low-power Schottky (LS) technology, it offers fast switching speeds with low power consumption. It is perfectly suited for 5V TTL digital logic applications and comes in a convenient Through-Hole DIP-14 package.

 

74LS00 Quad 2-Input NAND Gate

The 74LS00 integrated circuit (IC) is a fundamental building block in digital electronics, featuring four independent 2-input NAND gates. Based on reliable TTL (Transistor-Transistor Logic) architecture, it is widely used for performing basic logical operations, signal inversion, and constructing more complex digital logic systems.

Key Features

  • Operating Voltage: Standard 5V operation (Range: 4.75V to 5.25V).
  • Logic Type: Quad 2-Input NAND.
  • Technology: Low-power Schottky (LS) ensuring high speed (typical propagation delay of 10ns) with low power dissipation.
  • Mounting Type: Through-Hole, making it ideal for breadboard prototyping and custom PCBs.
  • Output Current: Supports up to 8mA (Low Level) and -0.4mA (High Level).

Pinout Overview

The DIP-14 package features the standard TTL power configuration, leaving 12 pins dedicated to the inputs and outputs of the four internal gates:

  • Pin 7: GND (Ground)
  • Pin 14: VCC (+5V Power Supply)
  • Pins 1, 2, 4, 5, 9, 10, 12, 13: Logic Inputs (A & B) for the 4 gates.
  • Pins 3, 6, 8, 11: Logic Outputs (Y) for the 4 gates.
