74AHC3G14DC-Q100H

Overview

The Nexperia 74AHC3G14DC-Q100H is a triple inverting Schmitt trigger housed in an 8-lead VSSOP (SOT765-1) package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, CMOS low power dissipation, and high noise immunity. It meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Triple inverter with Schmitt-trigger inputs providing high noise immunity
• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Overvoltage tolerant inputs allowing use as translators in mixed voltage environments

Applications

• Wave and pulse shaper for highly noisy environments
• Astable multivibrator circuits
• Monostable multivibrator circuits

Procurement Notes

Verify the specific suffix 'Q100H' against official Nexperia documentation to confirm it denotes the standard tape-and-reel packaging format compatible with automated assembly equipment. Confirm that the DC package designation corresponds to the SOT765-1 VSSOP8 form factor required for your PCB layout constraints before finalizing orders.

Selection Notes

Select this component when designing systems requiring robust signal conditioning in electrically noisy automotive or industrial environments. The Schmitt trigger functionality ensures clean output transitions from slowly changing input signals. Ensure the design accommodates the specified operating temperature range and supply voltage limits to maintain performance reliability.

Part Context

This part belongs to the Nexperia 74AHC_AHCT3G14-Q100 family of triple inverters. It shares functional characteristics with the 74AHCT3G14-Q100 variant but utilizes CMOS input levels rather than TTL levels. The DC package variant specifically utilizes the VSSOP8 footprint, distinguishing it from TSSOP8 or XSON8 package options available within the same logical family.

Replacement Considerations

The 74AHC3G14DP-Q100 serves as a package-compatible alternative if a TSSOP8 footprint is acceptable. For non-automotive general-purpose logic requirements, the standard 74AHC3G14DC may be considered, though it lacks the specific AEC-Q100 automotive qualification.
