74AHC14PW,112

Overview

The Nexperia 74AHC14PW,112 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 plastic thin shrink small outline package (SOT402-1) with 14 leads and a body width of 4.4 mm. It supports an ambient temperature range from -40 °C to +125 °C. Static characteristics include input leakage current maximums of 2.0 μA at extreme temperatures and supply current maximums of 40 μA. Dynamic performance specifies propagation delays ranging from 1.0 ns to 16.0 ns depending on load capacitance and supply voltage.

Feature Summary

• Hex inverter configuration with Schmitt-trigger inputs for noise immunity
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• CMOS low power dissipation with balanced propagation delays
• 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 '112' corresponds to the TSSOP14 package variant SOT402-1 when sourcing. Confirm that the required logic family matches the 74AHC series specifications rather than the 74AHCT series, as both share similar pinouts but differ in input voltage levels. Ensure environmental compliance requirements such as RoHS and REACH are met according to the latest product data sheet revision.

Selection Notes

Select this component when a hex inverter with hysteresis is required for signal conditioning or oscillation circuits. The wide supply voltage range accommodates systems operating between 2.0 V and 5.5 V. Consider the TSSOP14 package if space constraints require a thin profile compared to standard SO packages. Verify that the input voltage levels align with CMOS standards rather than TTL standards required by the AHCT variant.

Part Context

This part belongs to the 74AHC/AHCT14 family of hex inverters with Schmitt triggers. It shares functional similarities with other variants like the 74AHC14D and 74AHC14BQ, differing primarily in packaging technology. The PW suffix specifically denotes the TSSOP14 package, distinguishing it from SO14 or DHVQFN options within the same logical family.

Replacement Considerations

Direct substitutes include other 74AHC14 variants in different packages such as 74AHC14D (SO14) or 74AHC14BQ (DHVQFN14), provided the physical footprint allows. Cross-family replacements like 74VHC14 offer similar functionality but may have different electrical characteristics.
