MM74C14M

Inverter Gates Overview

The MM74C14M is a monolithic CMOS hex Schmitt trigger integrated circuit manufactured by onsemi (formerly Fairchild Semiconductor). It contains six independent inverters with Schmitt-trigger inputs, housed in a 14-lead Small Outline Integrated Circuit (SOIC) package. The device operates within a supply voltage range of 3.0V to 15V and supports an operating temperature range from -55°C to +125°C. Key electrical characteristics include a typical propagation delay of 80ns at 10V and guaranteed hysteresis of at least 0.2 times VCC.

Inverter Gates Feature Summary

• Features Schmitt-trigger inputs that provide noise immunity and clean signal transitions for slow-rise or slow-fall waveforms.
• Constructed using complementary MOS technology to ensure low power consumption across the wide operating voltage range.
• Includes input protection circuits against static discharge via diode clamps to VCC and GND.

Inverter Gates Applications

• Low power oscillator circuits
• Line receivers requiring noise filtering
• Signal conditioning for slow transition inputs

Inverter Gates Procurement Notes

Verify the specific manufacturer origin, as the component was originally produced by Fairchild Semiconductor before its semiconductor business acquisition. Confirm the package type matches the required footprint, as this part number specifically denotes the SOIC variant. Check RoHS compliance status relative to current manufacturing standards and verify the date code against project requirements.

Inverter Gates Selection Notes

Select this component when high noise immunity is required for digital signals with slow rise or fall times. It serves as a direct functional replacement for other hex Schmitt triggers in the 74C series. Ensure the design accommodates the wider supply voltage range up to 15V compared to standard 5V logic families.

Inverter Gates Part Context

This component belongs to the 74C series of CMOS logic devices, which are characterized by their wide operating voltage range compared to earlier NMOS or standard TTL technologies. The 'M' suffix indicates the 14-lead SOIC package format, distinguishing it from the PDIP version (N suffix). It is part of the broader family of hex inverters designed for general-purpose digital applications.

Inverter Gates Replacement Considerations

Direct pin-compatible substitutes include the MM74HC14M and MM74HCT14M. These variants offer faster switching speeds but operate at lower maximum supply voltages (typically 6V max). Verify voltage level compatibility and drive strength requirements before substituting.
