ON Semiconductor MM74HCT14M Hex Inverting Schmitt Trigger

The MM74HCT14M from ON Semiconductor is a high-performance, six-channel inverting Schmitt trigger, designed to provide noise immunity and a stable output for digital signal processing. This integrated circuit (IC) is a member of the HCT family, which means it is compatible with standard CMOS logic levels while being able to interface with TTL logic levels. The MM74HCT14M is a versatile component suitable for a wide range of applications in consumer electronics, automotive, and industrial systems.

Each inverter in the MM74HCT14M features a Schmitt trigger action, which enhances the noise threshold and transforms a noisy input into a clean digital signal. This is particularly useful in environments where electrical interference is common. The hysteresis characteristics of the Schmitt trigger inputs provide the advantage of slower input transition signals, allowing for better noise rejection and increased reliability of digital signals.

The MM74HCT14M operates over a broad voltage range from 4.5V to 5.5V, making it compatible with most 5V systems. It also offers a standard operating temperature range from -40°C to +85°C, ensuring its performance in various environmental conditions. The device is available in a compact SOIC-14 package, making it easy to integrate into space-constrained designs.

Key features of the MM74HCT14M include:

• Typical switching capability of 5.5 ns
• Low quiescent current consumption of 2 µA maximum
• High noise immunity characteristic of HCT logic
• Output drive capability of 10 LSTTL loads
• Robust latch-up performance that exceeds 250 mA
• ESD performance tested per JESD 22

ON Semiconductor's commitment to quality ensures that the MM74HCT14M meets stringent standards for performance and reliability. Whether it's used in signal conditioning, waveform shaping, or in circuits requiring a stable output from a noisy input, the MM74HCT14M is an excellent choice for designers looking for a high-quality Schmitt trigger inverter.
