Onsemi MM74HC02 Quad 2-Input NOR Gate IC 14-Pin SOIC

The Onsemi MM74HC02 Quad 2-Input NOR Gate IC is a CMOS logic integrated circuit with an 8 ns propagation delay, housed in a 14-pin SOIC package. It combines operating speeds comparable to LS-TTL logic families with the low power consumption typical of standard CMOS devices.

Overview

The ONSEMI MM74HC02M contains four 2-input NOR gates built on advanced silicon-gate CMOS technology. All gates feature buffered outputs, which support noise immunity and stable operation in electrically noisy environments. The buffered output stage can drive up to 10 LS-TTL loads directly.

Key Features

• High speed: 8 ns propagation delay
• Low power: maximum 20 µA quiescent current and 1 µA input current
• Robust output: minimum 4 mA high output current
• Pin-for-pin and function compatible with the 74LS series
• Internal diode clamps connected to VCC and ground help protect inputs from electrostatic discharge (ESD)
• Compact 14-pin SOIC (Small Outline Integrated Circuit) package

Operating Conditions

The IC operates across a supply voltage range of 2 V to 6 V and a temperature range of -40 °C to 125 °C, making it suitable for demanding industrial applications. The 74HC logic family is functionally and pin-out compatible with the 74LS family, allowing straightforward upgrades or replacements in existing circuits.

Dimensions and Weight

• Width: 3.3
• Depth: 1.5
• Height: 4.3
• Weight: 0.322 g

The Onsemi MM74HC02 Quad 2-Input NOR Gate IC is a practical choice for designers who need fast, low-power logic with industrial temperature tolerance and straightforward 74LS compatibility.
