74HCT2G14GW,125

Overview

The Nexperia 74HCT2G14GW,125 is a dual inverting Schmitt trigger IC from the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL-level inputs and CMOS outputs with clamp diodes for overvoltage protection. It is housed in a TSSOP6 plastic thin shrink small outline package (SOT363-2) with six leads. At 4.5 V with a 50 pF load capacitance, the maximum propagation delay is 32 ns at 25 °C.

Feature Summary

• Schmitt-trigger inputs convert slowly changing signals into sharply defined output waveforms
• TTL-compatible input levels ensure direct interfacing with standard logic systems
• High noise immunity suitable for operation in electrically noisy environments
• ESD protection exceeds 2000 V via Human Body Model and 1000 V via Charge Device Model

Applications

• Wave and pulse shaping for highly noisy environments
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify that the specific order code matches the HCT series requirements, as HC variants share similar packaging but differ in electrical characteristics. Confirm the SOT363-2 package designation aligns with PCB footprint constraints. Ensure the operating environment remains within the specified -40 °C to +125 °C range to maintain performance specifications. Check for any recent Product Change Notifications regarding marking or assembly transfers.

Selection Notes

Select this component when TTL-level compatibility is required alongside Schmitt-trigger functionality. The HCT series is appropriate for 5 V logic systems where noise immunity is critical. Verify that the 4.5 V to 5.5 V supply voltage range meets system power rails. Consider the TSSOP6 package dimensions if space is limited on the printed circuit board layout.

Part Context

This part belongs to the Nexperia 74HCT2G14 family of dual inverters. It shares the same physical package and pinout as the 74HC2G14 variant but utilizes different internal threshold voltages to support TTL logic levels. The GW suffix indicates the TSSOP6 package type, while the 125 denotes the extended industrial temperature range capability.

Replacement Considerations

The 74HC2G14GW,125 serves as a functional alternative with identical pinouts but requires CMOS-level input signals instead of TTL levels.
