74AHC1G14GV-Q100,1

Overview

The Nexperia 74AHC1G14GV-Q100,1 is a single inverter with Schmitt-trigger inputs, qualified to AEC-Q100 Grade 1. It operates on a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, CMOS low power dissipation, and symmetrical output impedance. Propagation delay is specified at 16.5 ns maximum (CL=50 pF, VCC=3.0-3.6 V) and 13.5 ns maximum (CL=50 pF, VCC=4.5-5.5 V). ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Schmitt-trigger input for jitter-free output signals
• Overvoltage tolerant inputs to 5.5 V

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74A (SOT753) package variant. Confirm that the Q100 designation aligns with automotive grade requirements for your target application environment. Ensure compatibility with the 2.0 V to 5.5 V supply voltage range and check if the -40 °C to +125 °C operating temperature meets system specifications.

Selection Notes

Select this component when a single-channel inverting function with hysteresis is required in mixed-voltage environments. The overvoltage tolerance allows interfacing with higher voltage logic without external level shifters. Consider the AEC-Q100 Grade 1 qualification for automotive reliability standards and the wide supply voltage flexibility for various digital systems.

Part Context

This part belongs to the 74AHC1G14-Q100 family of single inverters with Schmitt triggers. The GV suffix specifically denotes the SC-74A plastic surface-mounted package (SOT753), which provides five leads. This family is designed for automotive applications, offering high noise immunity and low power consumption compared to standard logic families.

Replacement Considerations

Direct substitutes include other 74AHC1G14 variants with different packages, such as 74AHC1G14GW-Q100 (TSSOP5) or 74AHC1G14GZ-Q100 (XSON5), provided the package footprint is adaptable. Cross-family replacements like 74HC1G14 require verification of voltage levels and switching characteristics.
