74LVC2G125DP-Q100H

Overview

The Nexperia 74LVC2G125DP-Q100H is a dual bus buffer and line driver featuring three-state outputs controlled by active-low enable inputs (nOE). It operates within a supply voltage range of 1.65 V to 5.5 V, supporting mixed 3.3 V and 5 V environments. The device incorporates Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C. Propagation delays range from 0.5 ns to 11.4 ns depending on voltage, with output drive capabilities up to ±24 mA at 3.0 V.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry enables partial power-down mode operation
• Schmitt-trigger inputs provide tolerance for slow signal transitions
• Overvoltage tolerant inputs allow direct interfacing with 5 V logic

Applications

• Mixed 3.3 V and 5 V translation applications
• Partial power-down system architectures
• Automotive electronic modules requiring Grade 1 reliability

Procurement Notes

Verify the specific suffix DP indicates the TSSOP8 package variant during procurement. Confirm that the Q100 designation aligns with required automotive grade specifications. Ensure the ordering code matches the exact temperature range and package dimensions specified in the manufacturer's official documentation before finalizing purchase orders.

Selection Notes

Select this component when designing systems requiring bidirectional buffering between different voltage domains. The inclusion of IOFF circuitry makes it suitable for applications where devices may be powered down while other parts of the circuit remain active. Verify that the input transition rates fall within the specified limits for the chosen supply voltage to maintain signal integrity.

Part Context

This part belongs to the 74LVC2G125-Q100 family of dual bus buffers. It shares functional similarities with other LVC series drivers but is distinctively qualified for automotive use under AEC-Q100 Grade 1. The DP suffix specifically denotes the TSSOP8 plastic thin shrink small outline package, distinguishing it from the DC VSSOP8 variant.

Replacement Considerations

The 74LVC2G125DC-Q100 serves as a package-compatible alternative using the VSSOP8 form factor. Both variants share identical electrical characteristics and functionality. Designers must verify pinout compatibility and thermal dissipation requirements when substituting between the TSSOP8 and VSSOP8 packages.
