ONSEMI MM74HC02 Quad 2-Input NOR Gate IC, 14-Pin SOIC

The ONSEMI MM74HC02M is a high-performance quad 2-input NOR gate integrated circuit. It utilises advanced silicon-gate CMOS technology to deliver operating speeds comparable to LS-TTL logic families while maintaining the exceptionally low power consumption characteristic of standard CMOS ICs. This makes it an ideal choice for modern digital designs where both speed and energy efficiency are critical.

All gates within the IC feature buffered outputs, which provide superior noise immunity and ensure stable operation in electrically noisy environments. This robust output stage also grants the device the capability to drive up to 10 LS-TTL loads directly, offering excellent fan-out and simplifying system design. The 74HC logic family is fully compatible, both functionally and in pin-out configuration, with the widely used standard 74LS logic family, allowing for straightforward upgrades or replacements in existing circuits.

To ensure long-term reliability, all inputs are protected from potential damage caused by electrostatic discharge (ESD) through internal diode clamps connected to VCC and ground. The IC operates across a broad supply voltage range from 2V to 6V and can function reliably in extreme temperatures from -40°C to 125°C, suiting it for demanding industrial applications.

Key Specifications & Features:

• High Speed: Features a fast 8ns propagation delay for responsive digital signal processing.
