MM74HCT14M

Inverter Gates Overview

The MM74HCT14M is a hex Schmitt-trigger inverter fabricated using high-performance silicon-gate CMOS technology by onsemi. It features six independent inverters within a single 14-pin package, designed for applications requiring noise immunity and signal conditioning. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports LSTTL-compatible input levels. Key electrical characteristics include a maximum propagation delay of 20 ns at 5 V with a 50 pF load, and symmetrical output drive currents of 4.8 mA for both high and low states. It functions reliably across an extended temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Integrates six independent Schmitt-trigger inverters for robust signal shaping and noise filtering
• Provides direct interface compatibility with LSTTL, CMOS, NMOS, and TTL logic families
• Utilizes high-performance silicon-gate CMOS technology for low power consumption and high speed

Inverter Gates Applications

• Level conversion between TTL or NMOS outputs and high-speed CMOS inputs
• Signal conditioning to square up slow rise and fall times
• Operation in noisy environments utilizing Schmitt trigger hysteresis

Inverter Gates Procurement Notes

Verify the specific manufacturer designation when sourcing, as Fairchild Semiconductor was the original developer of this part number before its acquisition by onsemi. Confirm that the component matches the 14-SOIC surface-mount package dimensions and pinout configuration required for your PCB layout. Ensure compliance with RoHS directives if environmental regulations apply to your assembly process.

Inverter Gates Selection Notes

Select this component when application requirements demand precise threshold control via Schmitt trigger action rather than standard switching thresholds. It is suitable for designs interfacing legacy TTL systems with modern CMOS logic where voltage level translation is necessary. Consider the 14-SOIC package constraints regarding thermal dissipation and board space availability during the selection phase.

Inverter Gates Part Context

This component belongs to the widely adopted 74HCT logic family, which bridges the performance gap between older TTL standards and newer CMOS technologies. The 'M' suffix specifically denotes the 14-lead Small Outline Integrated Circuit (SOIC) package variant. As a hex inverter, it consolidates multiple logic gates into a single footprint, reducing board space compared to discrete gate implementations.
