74AHC14PW/AUJ

Overview

The Nexperia 74AHC14PW/AUJ is a hex inverting Schmitt trigger integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes a TSSOP14 package (SOT402-1) with a body width of 4.4 mm. It supports an ambient temperature range from -40 °C to +125 °C. Static characteristics include input leakage currents up to 2.0 μA at maximum temperatures and supply currents up to 40 μA. Dynamic propagation delays are specified between 1.0 ns and 20.5 ns depending on load capacitance and voltage.

Feature Summary

• Hex inverter configuration with Schmitt-trigger inputs for noise immunity
• Overvoltage tolerant inputs allowing use in mixed voltage environments
• CMOS low power dissipation with balanced propagation delays
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Signal conditioning and waveform shaping
• Level translation in mixed voltage systems
• Relaxation oscillator circuits

Procurement Notes

Verify the specific ordering suffix AUJ corresponds to the TSSOP14 package variant SOT402-1 as defined in the official datasheet. Confirm that the component status aligns with current production availability, as lifecycle changes may affect long-term supply. Ensure design-in compliance with the recommended operating conditions regarding supply voltage and ambient temperature ranges.

Selection Notes

Select this component when hex inversion with hysteresis is required for noisy digital signals. The AHC logic family offers CMOS-level input compatibility suitable for 2.0 V to 5.5 V systems. Consider the TSSOP14 package if space-constrained surface-mount assembly is necessary. Verify that the input voltage requirements do not exceed the 5.5 V tolerance limit for the specific application environment.

Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices produced by Nexperia. It is functionally related to the 74AHCT14, which uses TTL-compatible input levels instead of CMOS levels. Both variants share identical pinouts and packaging options but differ in input threshold voltages. The PW/AUJ designation specifically identifies the thin shrink small outline plastic package variant.

Replacement Considerations

The 74AHCT14PW serves as a direct functional substitute if TTL-level input thresholds are acceptable. Other manufacturers producing JEDEC-compliant 74AHC14 devices in TSSOP14 packages may offer cross-references, provided electrical parameters match the original specifications.
