74HC2G125DP-Q100H

Overview

The Nexperia 74HC2G125DP-Q100H is a dual buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 6.0 V and supports CMOS input levels. The device includes input clamp diodes, allowing interface to voltages exceeding VCC using current-limiting resistors. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C. Packaged in an SOT505-2 TSSOP8 format, it offers high noise immunity and low power dissipation.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for extended temperature operation up to +125 °C
• Three-state outputs controlled by active-low nOE inputs to prevent bus contention
• Input clamp diodes enable direct interfacing with voltages higher than the supply rail

Applications

• Automotive electronic systems requiring robust signal buffering
• High-noise environments utilizing high noise immunity characteristics
• Mixed-voltage interfaces where input levels exceed the local supply voltage

Procurement Notes

Verify the specific suffix DP indicates the TSSOP8 package configuration. Confirm the Q100 designation aligns with automotive reliability requirements. Ensure the HC logic family matches the intended CMOS input level specifications for the target application design.

Selection Notes

Select this component when dual buffered signals require independent control via separate enable pins. The wide supply voltage range accommodates various system rails. Verify that the TSSOP8 footprint fits the available PCB space constraints compared to alternative packages like VSSOP8.

Part Context

This part belongs to the Nexperia 74HC2G125-Q100 series of dual buffers. It shares functional similarities with the HCT variant but utilizes CMOS input thresholds rather than TTL levels. The DP suffix specifically denotes the thin shrink small outline plastic package.

Replacement Considerations

The 74HC2G125DC-Q100H serves as a package-compatible alternative using the VSSOP8 form factor. For TTL-level input requirements, the 74HCT2G125DP-Q100H provides equivalent functionality with different threshold characteristics.
