74AHC14PW-Q100,118

Overview

The Nexperia 74AHC14PW-Q100,118 is a hex inverting Schmitt trigger housed in a TSSOP14 (SOT402-1) package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, balanced propagation delays, and high noise immunity. It meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Overvoltage tolerant inputs enabling use in mixed voltage environments
• Schmitt-trigger inputs transform slowly changing signals into sharply defined outputs

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component grade aligns with the target application's environmental requirements. Ensure design compatibility with the specified operating temperature range and supply voltage limits before finalizing procurement orders.

Selection Notes

Select this component when hex inversion with hysteresis is required in space-constrained designs. The TSSOP14 package offers a compact footprint suitable for surface-mount assembly. Consider the CMOS logic level input specifications and the wide supply voltage flexibility for system integration.

Part Context

This part belongs to the Nexperia 74AHC14-Q100 series, which includes variants in SO14 and DHVQFN packages. The PW suffix specifically denotes the TSSOP14 plastic thin shrink small outline package configuration. All variants share identical electrical characteristics and functional behavior.

Replacement Considerations

Direct substitutes include the 74AHC14D-Q100 (SO14 package) and 74AHC14BQ-Q100 (DHVQFN14 package). Verify pinout compatibility and thermal dissipation requirements when substituting between different package types.
