74LS00 / 74LS00N replacement chip, DIP-14, quadruple 2-Input positive-NAND gate used in arcade games and pinball machine repair.


The 74LS00 / 74LS00N is a widely used integrated circuit (IC) that belongs to the 74LS series of TTL (Transistor-Transistor Logic) devices. It is a quad 2-input NAND gate, meaning it contains four individual NAND gates, each with two inputs. The “74” in its name indicates that it is part of the 7400 series of ICs, and the “LS” signifies that it uses Low-Power Schottky (LS) technology.

Here are some key features and characteristics of the 74LS00:

  1. Quad 2-Input NAND Gates: The IC consists of four NAND gates, and each gate has two inputs (A and B) and one output (Y).
  2. Technology: The 74LS00 uses Low-Power Schottky (LS) technology. This technology is known for providing a balance between speed and power consumption.
  3. Power Supply Voltage: Typically operates with a power supply voltage of 4.75V to 5.25V.
  4. Logic Levels: In the TTL logic family, a HIGH (logical 1) is typically represented by a voltage close to the power supply voltage (Vcc), and a LOW (logical 0) is represented by a voltage close to ground (0V).
  5. Pin Configuration:
    • Pin 7: Ground (GND)
    • Pin 14: Power Supply Voltage (Vcc)
    • Pins 1, 2, 4, 5, 9, 10, 12, 13: Input and Output pins of the four NAND gates.
  6. Propagation Delay: The 74LS00 has a propagation delay, which is the time it takes for a change in input to result in a change in output. The specific value may vary, but it is generally in the range of a few nanoseconds.
  7. Operating Temperature Range: The 74LS00 is designed to operate within a specified temperature range. Common temperature ranges are 0°C to 70°C or -40°C to 85°C.
  8. Package Type: It is available in various package types, such as DIP (Dual Inline Package), SOIC (Small Outline Integrated Circuit), and others.

The 74LS00 is often used in digital electronic circuits for logic operations. Its versatile nature makes it suitable for a wide range of applications, including but not limited to arithmetic operations, data processing, and control logic in electronic systems. Keep in mind that technology has advanced since the introduction of the 74LS series, and newer families of ICs with improved features and performance have become available.
