74HC3G14DP-Q100H

Overview

The Nexperia 74HC3G14DP-Q100H is an automotive-grade triple inverting Schmitt trigger compliant with AEC-Q100 Grade 1 standards. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS input levels, clamp diodes for overvoltage interfacing, and high noise immunity. It is housed in an 8-lead TSSOP (SOT505-2) plastic thin shrink small outline package.

Feature Summary

• Automotive qualification according to AEC-Q100 Grade 1
• Triple inverter with Schmitt-trigger inputs for jitter-free signal shaping
• Wide supply voltage operation from 2.0 V to 6.0 V
• High ESD protection exceeding 2000 V HBM and 1000 V CDM

Applications

• Wave and pulse shaper for highly noisy environments
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the HC logic family aligns with system voltage requirements. Ensure design accounts for the specified temperature range and power dissipation limits during thermal analysis. Cross-reference marking codes for quality assurance.

Selection Notes

Select this component when CMOS input compatibility is required alongside Schmitt trigger hysteresis. It is suitable for mixed-voltage environments where input signals exceed VCC due to integrated clamp diodes. Consider the TSSOP package constraints for PCB layout and thermal management in dense automotive assemblies.

Part Context

This part belongs to the Nexperia 74HC3G14-Q100 series of triple inverters. It shares functional characteristics with the 74HCT3G14-Q100 but utilizes CMOS input thresholds rather than TTL levels. Both variants are designed for robust performance in demanding automotive electronic applications requiring reliable signal inversion.

Replacement Considerations

The 74HCT3G14DP-Q100H serves as a direct functional replacement if TTL input thresholds are acceptable. Verify pinout compatibility and ensure the alternative device meets the same AEC-Q100 Grade 1 qualification and operating temperature specifications.
