74HCT3G07DP-Q100H

Overview

The Nexperia 74HCT3G07DP-Q100H is a triple buffer with open-drain outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 2.0 V to 6.0 V and supports TTL input levels at 4.5 V to 5.5 V. The device is housed in an SOT505-2 (TSSOP8) package. Operating temperatures are specified from -40 °C to +125 °C. Static characteristics include low power dissipation and high noise immunity, with latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Triple buffer configuration featuring open-drain outputs
• Wide supply voltage operation from 2.0 V to 6.0 V
• High noise immunity with ESD protection exceeding 2000 V HBM

Applications

• Automotive electronic systems requiring robust logic buffering
• Mixed-voltage signal interfacing using current limiting resistors
• General-purpose digital buffering in industrial environments

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's latest ordering information to confirm packaging details such as reel or cut tape specifications. Ensure the design accounts for the TSSOP8 package thermal derating requirements above 96 °C. Confirm that the application voltage does not exceed the absolute maximum ratings defined in the datasheet to prevent permanent damage.

Selection Notes

Select this component when open-drain output capability is required for wired-AND configurations or level shifting. The HCT variant ensures compatibility with TTL logic levels at standard 5 V supplies. Consider the wide operating temperature range and automotive qualification if the deployment environment involves harsh conditions or strict reliability standards.

Part Context

This part belongs to the Nexperia 74HCT3G07-Q100 family of triple buffers. It shares functional similarities with other single-function logic ICs but is distinguished by its open-drain output structure and automotive grade certification. The DP suffix indicates the TSSOP8 package type, differentiating it from DC (VSSOP8) variants within the same logical family.

Replacement Considerations

Direct substitutes include the 74HC3G07DP-Q100H for CMOS-level inputs or the 74HCT3G07DC-Q100H for VSSOP8 packaging. Verify pinout compatibility and electrical parameters before substitution.
