CD74HC14ME4

Inverter Gates Overview

The CD74HC14ME4 is a high-speed CMOS logic device manufactured by Texas Instruments, belonging to the HC series. It contains six independent inverting Schmitt-trigger gates housed in a 14-pin SOIC surface-mount package. The component operates within a supply voltage range of 2 V to 6 V and supports an extended industrial temperature range from -55 °C to +125 °C. Key electrical characteristics include a maximum propagation delay of 29 ns at 6 V with a 50 pF load, and symmetrical output drive currents of ±5.2 mA. The device complies with RoHS directives and features low static power consumption typical of CMOS technology.

Inverter Gates Feature Summary

• Integrates six independent inverters with Schmitt-trigger inputs for noise immunity
• High-speed CMOS construction ensures low power dissipation
• Extended operating temperature range suitable for industrial environments

Inverter Gates Applications

• Signal conditioning and waveform shaping
• Oscillator circuits requiring hysteresis
• Pulse width modulation signal generation

Inverter Gates Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per Texas Instruments documentation. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Check current production status, as lifecycle notifications may affect long-term availability. Ensure input voltage levels remain within specified limits relative to the supply voltage to prevent latch-up or damage.

Inverter Gates Selection Notes

Select this component when six isolated inverting channels with hysteresis are required in a compact surface-mount form factor. The HC series offers compatibility with standard 5 V logic systems while supporting lower voltage operation down to 2 V. Consider the 29 ns propagation delay for timing-critical applications. Verify that the SOIC-14 thermal performance meets your board's heat dissipation capabilities under maximum load conditions.

Inverter Gates Part Context

This part belongs to the CD74HC14 family of hex Schmitt-triggered inverters. The 'E4' suffix typically denotes environmental compliance, specifically lead-free packaging and RoHS adherence. It shares functional similarities with other variants like CD74HC14M or SN74HC14, differing primarily in packaging style and manufacturing specifications defined by Texas Instruments.

Inverter Gates Replacement Considerations

Cross-reference with SN74HC14NS for DIP alternatives or CD74HC14MT for tape-and-reel SOIC options. Verify pinout compatibility and electrical parameters before substitution. Check for any obsolescence notices affecting the original part number.
