74LVC2G126DP-Q100H

Overview

The Nexperia 74LVC2G126DP-Q100H is a dual buffer and line driver featuring three-state outputs controlled by active-high output enable inputs. It operates within a supply voltage range of 1.65 V to 5.5 V, with overvoltage tolerant inputs up to 5.5 V. The device incorporates Schmitt-trigger action for noise immunity and IOFF circuitry to prevent backflow during partial power-down. Qualified to AEC-Q100 Grade 1 standards, it supports an ambient temperature range from -40 °C to +125 °C and is housed in an SOT505-2 TSSOP8 package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry enables safe partial power-down mode operation
• Schmitt-trigger inputs provide tolerance for slow signal transitions
• Inputs tolerate voltages up to 5.5 V regardless of supply level

Applications

• Mixed 3.3 V and 5 V bus translation environments
• Automotive electronic systems requiring Grade 1 reliability
• Partial power-down applications preventing backflow current

Procurement Notes

Verify the specific suffix DP-Q100H corresponds to the TSSOP8 (SOT505-2) package variant. Confirm that the required operating temperature range meets the specified -40 °C to +125 °C limit. Ensure input drive levels are compatible with the 5.5 V overvoltage tolerance specification. Check for any recent product change notices affecting marking codes or pin configurations.

Selection Notes

Select this component when dual-channel buffering with high noise immunity is required in automotive designs. The wide supply voltage range allows direct interfacing between different logic families without external level shifters. The inclusion of IOFF functionality makes it suitable for systems requiring low standby currents during power-down states. Verify that the TSSOP8 footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the Nexperia 74LVC2G126-Q100 family of automotive-grade logic buffers. It shares functional characteristics with other members of the LVC series but is specifically qualified for harsh automotive environments. The DP suffix identifies the thin shrink small outline plastic package, distinguishing it from VSSOP variants within the same logical family.

Replacement Considerations

The 74LVC2G126DC-Q100H serves as a package alternative using the VSSOP8 form factor.
