74ls02 74ahs02 7402 Quad 2-input Nor Gate

74LS02 / 74AHC02 / 7402 – Quad 2-Input NOR Gate IC

The 74LS02 (or 74AHC02, 7402 in some variants) is a Quad 2-input NOR Gate integrated circuit. It contains four independent NOR gates, each with two inputs, and provides the output of the logical NOR operation. The NOR gate is a basic digital logic gate that outputs high (1) only when both inputs are low (0); otherwise, the output is low (0). This IC is widely used for various logical functions in digital circuits, and it belongs to the 74LS and 74AHC series, offering high-speed performance with low power consumption.

Key Features:

• Quad 2-Input NOR Gates: The IC contains four independent NOR gates, each with two inputs, providing efficient logic operations in a compact package.
• High-Speed Operation: The 74LS02 and 74AHC02 are designed for high-speed performance, ensuring fast response times in logic circuits.
• Low Power Consumption: Built for low power consumption while maintaining high-speed operation, making it ideal for energy-efficient digital systems.
• Wide Supply Voltage Range: The IC operates within a voltage range of 4.75V to 5.25V (for 74LS02) and 2V to 5.5V (for 74AHC02), making it compatible with TTL and CMOS systems.
• Output Drive Capability: The outputs can drive standard TTL loads with high current drive capability, ensuring reliable signal transmission.
• Low Input Current: Designed with low input current, reducing the need for external current-limiting resistors and enabling easy interfacing with other logic circuits.
• TTL and CMOS Compatible: Compatible with both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic families, allowing for flexibility in integration.

Applications:
