MM74C914N

Inverter Gates Overview

The MM74C914N is a monolithic CMOS Hex Schmitt trigger housed in a 14-lead Plastic Dual-In-Line (PDIP) package. It operates within a supply voltage range of 3V to 15V and supports an operating temperature range from -40°C to +85°C. The device features extended input voltage protection, allowing levels between VCC −25V and GND + 25V. Hysteresis is guaranteed at a minimum of 0.2 VCC, with typical propagation delays ranging from 80ns to 400ns depending on the supply voltage.

Inverter Gates Feature Summary

• Special input protection scheme allows input voltages to exceed power supply rails by up to 25V
• High noise immunity with guaranteed hysteresis for signal conditioning
• Low power consumption compatible with driving multiple low-power TTL loads

Inverter Gates Applications

• Voltage level shifting between mismatched power supplies
• Signal conditioning for noisy environments requiring Schmitt trigger action
• Interface circuits involving inputs exceeding standard logic supply limits

Inverter Gates Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the device is also available in SOIC packaging. Confirm RoHS compliance status and lead-free markings if required for your assembly process. Check current availability as this component may be subject to lifecycle changes or limited distribution channels.

Inverter Gates Selection Notes

Select this component when applications require robust input protection against overvoltage conditions beyond the supply rails. It is suitable for interfacing sensors or signals that may swing significantly higher or lower than the system ground or VCC. Ensure the required hysteresis width meets the noise rejection needs of the specific application environment.

Inverter Gates Part Context

This part belongs to the MM74C91x series of hex Schmitt triggers manufactured originally by Fairchild Semiconductor and now associated with onsemi. It provides six independent inverters with Schmitt-trigger inputs in a single package, designed for high-noise immunity and extended voltage tolerance compared to standard logic families.

Inverter Gates Replacement Considerations

The MM74C914M is the SOIC version of this device. Verify pinout compatibility and package dimensions when substituting DIP packages with surface-mount alternatives.
