The 74LS20 is a dual four-input NAND gate integrated circuit from the 74LS series of transistor-transistor logic (TTL) devices. This component is used in digital logic circuits to perform the logical NAND operation on four input signals for each of the two gates contained within the package.
- Dual four-input NAND gate configuration
- Standard 74LS series logic component
- Suitable for breadboarding and PCB assembly
