74AHCV14APWJ

Overview

The Nexperia 74AHCV14APWJ is a hex inverting Schmitt trigger housed in a TSSOP14 (SOT402-1) package. It operates within a supply voltage range of 1.8 V to 5.5 V and supports mixed-mode voltage operation on all ports. The device features IOFF circuitry for partial power-down applications, preventing damaging backflow currents. It provides high noise immunity with typical propagation delays of 3.2 ns at 5 V and withstands latch-up currents exceeding 250 mA per JESD 78 Class II.

Feature Summary

• Hex inverting Schmitt trigger configuration
• IOFF circuitry for partial power-down mode
• Overvoltage tolerant inputs

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current ordering information to confirm packaging details such as tape and reel specifications or cut tape availability. Ensure the component status remains active before finalizing procurement plans. Cross-reference the 12NC code with official distributor catalogs to validate the exact physical package dimensions and lead finish requirements for your assembly process.

Selection Notes

Select this component when designing circuits requiring signal conditioning with hysteresis to eliminate noise-induced glitches. The wide supply voltage range allows compatibility with various logic families. Verify that the input transition rates fall within the specified limits for the chosen operating voltage to ensure proper Schmitt-trigger action and reliable switching performance across the full industrial temperature range.

Part Context

This part belongs to the 74AHCV series, which represents high-speed CMOS logic optimized for low power consumption and wide voltage operation. The AHCV family is designed to bridge different voltage domains while maintaining fast switching speeds. The inclusion of Schmitt triggers distinguishes it from standard inverters by providing defined threshold voltages for both rising and falling input signals.

Replacement Considerations

Check for 74AHCV14AD or 74AHCV14ABQ if alternative packages are required, noting these were removed from the product specification in earlier revisions. Ensure any substitute maintains the TSSOP14 footprint and identical electrical characteristics for direct pin-to-pin replacement without circuit modification.

FAQ

How does the IOFF circuitry function during partial power-down?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.

What is the maximum latch-up current rating?

The latch-up performance exceeds 250 mA per JESD 78 Class II.
