74AHCT3G14DC-Q100H

Overview

The Nexperia 74AHCT3G14DC-Q100H is a triple inverting Schmitt trigger housed in an SOT765-1 (VSSOP8) package. It operates within a supply voltage range of 2.0 V to 5.5 V and features TTL input levels with overvoltage tolerance up to 5.5 V. The device meets AEC-Q100 Grade 1 qualification for automotive use, supporting ambient temperatures from -40 °C to +125 °C. It provides symmetrical output impedance, high noise immunity, and balanced propagation delays.

Feature Summary

• Triple inverter configuration with Schmitt-trigger inputs for jitter-free signal conversion
• Automotive grade qualification compliant with AEC-Q100 standards
• Overvoltage tolerant inputs enabling operation in mixed voltage environments
• High noise immunity and CMOS low power dissipation characteristics

Applications

• Wave and pulse shaping in highly noisy environments
• Astable multivibrator circuits
• Monostable multivibrator circuits

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's current documentation to confirm packaging details such as reel or cut tape specifications. Ensure the ordering part number matches the required temperature range and package variant. Confirm compliance requirements including RoHS and REACH status directly with the supplier before finalizing procurement orders.

Selection Notes

Select this component when a compact triple inverter with Schmitt triggers is required for automotive applications. The DC package offers a very thin shrink small outline form factor suitable for space-constrained designs. Verify that TTL input logic levels are compatible with the driving source voltage compared to standard CMOS variants.

Part Context

This device belongs to the Nexperia 74AHC_AHCT3G14-Q100 family of triple inverting Schmitt triggers. It shares functional similarities with other members like the 74AHCT3G14DP-Q100 but utilizes the SOT765-1 VSSOP8 package instead of the TSSOP8 option. The family is designed for robust performance in demanding automotive electronic systems requiring reliable signal inversion.

Replacement Considerations

The 74AHCT3G14DP-Q100 serves as a direct functional alternative if the TSSOP8 package is acceptable. Other single-gate inverters from the same series may require circuit redesign due to pinout differences.
