ONSEMI MM74HC14M Hex Schmitt Inverter Logic IC, 14-Pin SOIC

The ONSEMI MM74HC14M is a high-performance hex inverting Schmitt trigger integrated circuit. It utilises advanced silicon-gate CMOS technology to deliver the low power dissipation and high noise immunity characteristic of standard CMOS, while offering the robust drive capability to handle up to 10 LS-TTL loads. This makes it an exceptionally efficient and reliable component for digital logic design.

As part of the 74HC logic family, the MM74HC14M is both functionally and pin-out compatible with the standard 74LS logic family, ensuring easy integration into existing circuit designs. All inputs are protected against damage from electrostatic discharge (ESD) through internal diode clamps connected to VCC and ground, enhancing its durability and handling safety.

Key Performance Characteristics

• High Speed: Features a typical propagation delay of just 13ns, enabling fast signal processing.
• Low Power Consumption: Achieves a maximum low quiescent current of 20µA and a maximum low input current of 1µA, making it ideal for battery-powered or energy-sensitive applications.
• Strong Drive: A fanout capability of 10 LS-TTL loads provides excellent output drive strength.
• Noise Immunity: Incorporates Schmitt trigger inputs with a typical hysteresis voltage of 0.9V at VCC = 4.5V, which significantly improves noise margin and ensures clean signal transitions in noisy environments.

Encapsulated in a compact 14-pin SOIC (Small Outline Integrated Circuit) package, this IC is designed for efficient use of board space. Its wide operating temperature range from -55°C to 125°C and broad supply voltage range from 2V to 6V provide outstanding flexibility for use in commercial, industrial, and extended-temperature applications.
