74AHCT14D-Q100,118

Overview

The Nexperia 74AHCT14D-Q100,118 is a hex inverting Schmitt trigger integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and functions across an ambient temperature range of -40 °C to +125 °C. The device utilizes a SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. It features TTL input levels and overvoltage tolerant inputs up to 5.5 V. Propagation delay is specified at a maximum of 10.0 ns under a 50 pF load condition.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1
• Hex inverter configuration with Schmitt-trigger inputs for noise immunity
• Overvoltage tolerant inputs enabling operation in mixed voltage environments
• CMOS low power dissipation with balanced propagation delays

Applications

• Wave and pulse shapers

Selection Notes

Select this component when a hex inverter with Schmitt-trigger action is required for automotive or industrial applications operating at 5 V logic levels. The AHCT series ensures TTL-compatible input thresholds while maintaining CMOS performance characteristics. Ensure the design accommodates the specified 5.5 V maximum input voltage tolerance if interfacing with higher voltage sources.

Part Context

This part belongs to the Nexperia 74AHC(AHCT)14-Q100 family of hex inverters. The 'D' designation indicates the SO14 surface-mount package variant, while the 'Q100' suffix confirms its qualification for automotive use according to AEC-Q100 standards. The ',118' suffix typically denotes the specific tape and reel packaging format used for automated assembly processes.

Replacement Considerations

Direct replacements include other 74AHCT14 variants from different manufacturers that meet AEC-Q100 Grade 1 requirements and offer identical pinouts and electrical specifications. Verify package compatibility (SO14/SOT108-1) and ensure input threshold levels match the system's TTL logic requirements.
