74HCT14PW,118

Overview

The Nexperia 74HCT14PW,118 is a hex inverting Schmitt trigger integrated circuit belonging to the HCT logic family. It features six independent inverters with Schmitt-trigger inputs, designed for CMOS low power dissipation and high noise immunity. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. It is housed in a TSSOP14 plastic thin shrink small outline package (SOT402-1) containing 14 leads with a body width of 4.4 mm.

Feature Summary

• Schmitt-trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• CMOS technology ensures low power dissipation and high noise immunity
• Input clamp diodes enable interfacing to voltages exceeding VCC using current limiting resistors

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 meets RoHS compliance standards as indicated in official documentation. Ensure the procurement channel provides valid traceability data for the manufacturing lot. Cross-reference the part number against the latest Nexperia product status to confirm active production availability.

Selection Notes

Select this component when TTL-compatible input levels are required alongside Schmitt-trigger hysteresis for signal conditioning. The HCT series ensures compatibility with standard TTL logic families while maintaining CMOS performance characteristics. Verify that the operating voltage range aligns with the system's 5 V supply rails and that the thermal requirements fit the intended application environment.

Part Context

This component is part of the broader 74HCT14 series manufactured by Nexperia. It shares functional specifications with other packages such as SO14 and DHVQFN14 variants. The PW suffix specifically denotes the TSSOP14 package configuration. All variants within the series maintain identical electrical characteristics and pinout assignments for design flexibility.

Replacement Considerations

Direct replacements include other 74HCT14 variants from Nexperia or equivalent hex Schmitt trigger inverters from other manufacturers. Ensure any substitute maintains the same TSSOP14 footprint and pin configuration. Verify that the alternative component meets the same HCT logic level requirements and operating temperature specifications.
