74HCT2G125DC-Q100H

Overview

The Nexperia 74HCT2G125DC-Q100H is a dual buffer and line driver featuring three-state outputs, housed in an 8-lead VSSOP (SOT765-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device utilizes TTL input levels and provides high noise immunity with low power dissipation. Dynamic characteristics include a maximum propagation delay of 38 ns at 4.5 V and a typical transition time of 15 ns.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Three-state outputs controlled by active LOW enable inputs
• TTL-compatible input switching levels for direct interfacing
• ESD protection exceeding 2000 V via Human Body Model

Applications

• Automotive electronic systems requiring qualified logic components
• Bus-oriented transmission lines
• Clock distribution circuits
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'DC' corresponds to the VSSOP8 package variant during procurement. Confirm that the H suffix indicates halogen-free status. Ensure the ordering code matches the required temperature grade and automotive qualification level specified in the manufacturer's official documentation.

Selection Notes

Select this component when TTL-level compatibility is required alongside automotive reliability standards. The VSSOP8 package offers a compact footprint suitable for space-constrained designs. Verify that the 4.5 V to 5.5 V operating range aligns with the system's power supply specifications.

Part Context

This part belongs to the Nexperia 74HCT2G125-Q100 family of dual buffers. It shares functional similarities with other members like the 74HC2G125 but differs in input threshold requirements. The DC package variant distinguishes it from the DP (TSSOP8) version while maintaining identical electrical performance characteristics.

Replacement Considerations

The 74HCT2G125DP-Q100H serves as a pin-compatible alternative utilizing the TSSOP8 package.
