MM74HCT14MX

Inverter Gates Overview

The MM74HCT14MX is a hex inverter integrated circuit featuring Schmitt-trigger inputs, manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 4.5V to 5.5V and utilizes a 14-TSSOP surface-mount package. The device contains six independent inverters with one input each. Key electrical characteristics include a maximum propagation delay of 20ns at 5V with a 50pF load, output currents of 4.8mA for both high and low states, and a maximum quiescent current of 1µA. It functions reliably across an operating temperature range of -40°C to +85°C.

Inverter Gates Feature Summary

• Incorporates Schmitt-trigger inputs to provide noise filtering and hysteresis for clean signal transitions.
• Provides six independent inverting channels within a single compact surface-mount package.
• Utilizes advanced CMOS technology to ensure high noise immunity and low power consumption.

Inverter Gates Applications

• Signal conditioning for noisy digital environments requiring hysteresis
• Waveform shaping from slow or distorted input signals
• Pulse generation circuits

Inverter Gates Procurement Notes

Verify the manufacturer part number MM74HCT14MX against official datasheets to confirm the TSSOP-14 package and HCT logic family specifications. Ensure the component matches the required 4.5V to 5.5V supply voltage range and Schmitt-trigger functionality. Cross-reference the manufacturer designation, as Fairchild Semiconductor assets are managed by onsemi, to guarantee authenticity and correct technical parameters.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger action is necessary to eliminate noise-induced glitches on inverter inputs. The HCT series ensures compatibility with TTL logic levels while maintaining CMOS power efficiency. Verify that the 14-TSSOP package fits the board layout constraints and that the 4.8mA drive capability meets the load requirements for the specific application.

Inverter Gates Part Context

This component belongs to the 74HCT logic family, which bridges the performance gap between standard CMOS and Low-power Schottky TTL. The 'M' suffix typically denotes the TSSOP package variant, while 'X' often indicates tape-and-reel packaging. As a hex inverter, it serves as a fundamental building block for digital logic inversion and signal processing tasks.

Inverter Gates Replacement Considerations

Compatible substitutes include MM74HC14MX (CMOS version) and MM74HCT14MTCX (TSSOP variant). Verify pinout compatibility and logic level thresholds before substitution.

Inverter Gates FAQ

What is the primary function of the Schmitt trigger in this IC?

The Schmitt trigger provides hysteresis, which filters out noise and ensures clean, sharp output transitions even when the input signal changes slowly or contains interference.

Does the MM74HCT14MX support 3.3V logic levels?

No, the MM74HCT14MX requires a supply voltage of 4.5V to 5.5V. For 3.3V applications, the HC series (e.g., MM74HC14MX) should be used instead.
