MM74HCT14M

Inverter Gates Overview

The MM74HCT14M is a hex inverter integrated circuit manufactured by Fairchild Semiconductor, belonging to the 74HCT logic series. It features six independent inverters with Schmitt-trigger inputs, housed in a 14-SOIC surface-mount package. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 20ns at 5V with a 50pF load, and output currents of 4.8mA for both high and low states. The static current consumption is limited to 1µA, and it supports an operating temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Schmitt-trigger input functionality provides noise filtering and hysteresis for clean signal transitions.
• CMOS technology ensures low power consumption with minimal static current draw.
• Surface-mount SOIC-14 packaging facilitates automated assembly and compact circuit board designs.

Inverter Gates Applications

• Signal conditioning and waveform shaping for noisy digital environments
• Pulse generation and timing circuits requiring precise threshold control
• Oscillator circuits utilizing the hysteresis characteristics for stable frequency generation

Inverter Gates Procurement Notes

Verify the manufacturer designation on the component marking, as Fairchild Semiconductor's logic division operations have transitioned to onsemi. Ensure the ordering suffix corresponds to the specific tape-and-reel or bulk packaging requirements for your production line. Confirm RoHS compliance status through the official datasheet provided by the current rights holder to meet environmental regulations.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger action is required to eliminate noise on slow-rising digital signals. The HCT series offers TTL-compatible logic levels while maintaining CMOS low-power advantages. Compare against the standard MM74HC14M if higher speed or wider voltage ranges are needed, noting that HC series devices may have different switching thresholds compared to the HCT family.

Inverter Gates Part Context

This part belongs to the widely adopted 74HCT logic family, designed for compatibility with TTL systems using CMOS technology. The 'M' suffix indicates the 14-pin Small Outline Integrated Circuit (SOIC) package format. As a legacy Fairchild product, availability may now be managed under onsemi distribution channels, reflecting corporate restructuring in the semiconductor industry.

Inverter Gates Replacement Considerations

The MM74HCT14MTCX is a verified equivalent part number offering identical logical function and pinout but utilizes a TSSOP-14 package instead of SOIC-14. Verify mechanical footprint compatibility before substitution. Other generic 74HCT14 equivalents from different manufacturers may require verification of output drive strength and propagation delay specifications.
