MM74HCT14MTCX

Inverter Gates Overview

The MM74HCT14MTCX is a hex Schmitt-trigger inverter manufactured by onsemi, belonging to the 74HCT logic family. It features six independent inverters with Schmitt-trigger inputs for noise immunity and slow signal conditioning. The device operates within a supply voltage range of 4.5V to 5.5V. It provides symmetrical output drive currents of 4.8mA at both high and low states. The maximum propagation delay is 20ns at 5V with a 50pF load. It is housed in a 14-TSSOP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Hex configuration providing six independent inverting channels in a single package
• Schmitt-trigger input architecture ensures clean switching and hysteresis for noisy or slowly changing signals
• CMOS technology delivers low static current consumption of 1µA maximum
• Surface-mount TSSOP-14 packaging facilitates automated assembly and compact board design

Inverter Gates Applications

• Signal conditioning for waveforms with slow rise or fall times
• Noise filtering in digital communication interfaces
• Pulse generation and timing circuits requiring precise threshold control
• Oscillator circuits utilizing RC feedback networks

Inverter Gates Procurement Notes

Verify the complete part number including suffixes such as 'X' which indicates tape-and-reel packaging. Confirm RoHS compliance status and material declaration requirements specific to your region. Check moisture sensitivity level (MSL) ratings if lead-free soldering processes are mandated. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger functionality is required within the 74HCT voltage domain. It is suitable for applications needing robust noise immunity compared to standard inverters. Consider the 14-TSSOP footprint constraints during layout. Verify that the 4.5V minimum supply voltage aligns with the system power rails. Evaluate thermal performance if multiple inverters are driven simultaneously near maximum ratings.

Inverter Gates Part Context

This device is part of onsemi's extensive 74HCT series, designed for compatibility with 74LS logic families while offering CMOS advantages. The MM74HCT14 variant specifically addresses applications requiring hysteresis. It shares pinout compatibility with other 14-pin logic devices like the MM74HCT04, simplifying board redesigns where inversion type changes are necessary without altering physical layout.

Inverter Gates Replacement Considerations

Direct substitutes include the MM74HC14MTCX, though it belongs to the HC family with different voltage ranges. Other compatible options may exist within the same manufacturer's portfolio or from alternative vendors producing equivalent 74HCT14 parts in TSSOP-14 packages. Always verify electrical parameters and pin configurations before substitution.
