74AHCT1G14GV,125

Overview

The Nexperia 74AHCT1G14GV,125 is a single inverter with Schmitt-trigger inputs housed in a SC-74A (SOT753) package. It operates within a supply voltage range of 4.5 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, allowing use in mixed-voltage environments. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C and a maximum supply current of 40 μA. Dynamic performance specifies a propagation delay of 11.0 ns maximum at 5.5 V with a 50 pF load.

Feature Summary

• Incorporates Schmitt-trigger inputs for high noise immunity and clean signal transitions.
• Features overvoltage tolerant inputs compatible with 5.5 V signals while operating at lower supply voltages.
• Provides symmetrical output impedance and CMOS low power dissipation.
• Includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when TTL-compatible logic levels are required in a CMOS system. The AHCT series ensures compatibility with standard TTL outputs while offering the benefits of CMOS technology. Ensure the application environment stays within the specified 4.5 V to 5.5 V supply range and that input signals do not exceed the 5.5 V tolerance limit.

Part Context

This part belongs to the Nexperia 74AHC/AHCT1G14 family of single inverters with Schmitt triggers. The 'GV' suffix indicates the SC-74A (SOT753) surface-mount package. The 'AHCT' designation distinguishes it from the AHC series by utilizing TTL input switching levels rather than CMOS levels, making it suitable for interfacing with legacy TTL logic families.
