74HCT1G14GW,165

Overview

The Nexperia 74HCT1G14GW,165 is a single inverter with Schmitt-trigger input. It 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. The device features TTL input levels and includes clamp diodes for overvoltage tolerance. Static characteristics specify a maximum supply current of 20 µA at 5.5 V. Dynamic performance indicates a maximum propagation delay of 51 ns at 4.5 V with a 50 pF load.

Feature Summary

• Schmitt-trigger inputs transform slowly changing signals into sharply defined output waveforms.
• TTL input switching levels ensure compatibility with standard logic families.
• Input clamp diodes enable interface to voltages exceeding the supply rail using current limiting resistors.

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure the selected variant matches the required operating temperature range and electrical parameters for the target application environment.

Selection Notes

Select this component when TTL-compatible logic inversion with noise immunity is required. The Schmitt trigger function is suitable for applications involving slow-rise or slow-fall input signals. Verify that the 5-TSSOP package dimensions fit the available PCB footprint and that the 4.5 V to 5.5 V supply range aligns with the system power architecture.

Part Context

This part belongs to the Nexperia 74HCT1G14 series of single-function inverters. It utilizes CMOS technology to provide low power dissipation while maintaining high noise immunity. The device is designed for surface-mount assembly and is compliant with JEDEC standards for operation across specified voltage ranges.

Replacement Considerations

Cross-reference with other 74HCT1G14 variants from different manufacturers if pinout and electrical specifications match. Verify package compatibility (SOT353-1) and thermal derating requirements before substitution.

FAQ

How does the device handle input voltages higher than VCC?

The inputs include clamp diodes, which allow the use of current-limiting resistors to interface with voltages exceeding VCC without damaging the device.

What is the purpose of the Schmitt trigger in this inverter?

The Schmitt trigger action ensures that slowly changing input signals are converted into sharply defined, jitter-free output signals by providing distinct positive-going and negative-going threshold voltages.
