74HCT3G14DP-Q100H

Inverter Gates Overview

The Nexperia 74HCT3G14DP-Q100H is a triple inverting Schmitt trigger integrated circuit designed for automotive applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-level inputs, clamp diodes on all inputs, and high noise immunity. It is housed in an 8-lead TSSOP plastic thin shrink small outline package (SOT505-2).

Inverter Gates Feature Summary

• Qualified to AEC-Q100 Grade 1 standards for automotive use.
• Schmitt-trigger inputs convert slowly changing signals into sharply defined outputs.
• Inputs include clamp diodes allowing interface to voltages exceeding VCC via current limiting resistors.
• ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

Inverter Gates Applications

• Wave and pulse shaping in highly noisy environments.
• Astable multivibrators.
• Monostable multivibrators.

Inverter Gates Procurement Notes

Verify the specific suffix 'H' against the manufacturer's latest documentation to confirm reel packaging specifications. Ensure the design accommodates the specified operating temperature range of -40 °C to +125 °C. Confirm that the TSSOP8 footprint matches the SOT505-2 mechanical drawing provided in the datasheet before finalizing the layout.

Inverter Gates Selection Notes

Select this component when TTL-compatible logic levels are required alongside Schmitt-trigger hysteresis for signal conditioning. The HCT series ensures compatibility with standard TTL output drivers. Verify that the application environment meets the AEC-Q100 Grade 1 qualification requirements and that the thermal dissipation limits for the TSSOP8 package are respected under maximum load conditions.

Inverter Gates Part Context

This part belongs to the Nexperia 74HCT3G14-Q100 family of triple inverters. It shares functional characteristics with the 74HC3G14-Q100 variant but utilizes HCT technology for TTL input levels. The product line is specifically engineered for robust performance in automotive electronics, offering high noise immunity and compliance with strict automotive reliability standards.

Inverter Gates Replacement Considerations

The 74HCT3G14DP,125 is a non-automotive qualified equivalent available in the same TSSOP8 package. Designers must verify if the loss of AEC-Q100 Grade 1 qualification is acceptable for the target application environment.
