74LVC1G125GZ-Q10YL

Overview

The Nexperia 74LVC1G125GZ-Q10YL is a single buffer and line driver featuring a three-state output, designed for automotive applications. It operates within a supply voltage range of 1.65 V to 5.5 V and supports overvoltage tolerant inputs up to 5.5 V. The device incorporates Schmitt-trigger action at all inputs to ensure tolerance for slower input rise and fall times. It includes IOFF circuitry that disables the output during partial power-down mode to prevent potentially damaging backflow current. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1) for use in automotive environments
• IOFF circuitry provides partial power-down mode operation by disabling outputs to prevent backflow current
• Schmitt-trigger action at all inputs ensures tolerance for slower input rise and fall times
• Overvoltage tolerant inputs allow direct interface with TTL levels and mixed 3.3 V and 5 V environments

Applications

• Automotive electronic systems requiring qualified logic buffers
• Mixed 3.3 V and 5 V translation environments
• Partial power-down applications utilizing IOFF functionality

Procurement Notes

Verify the specific ordering suffix GZ-Q10YL corresponds to the XSON5 package (SOT8065-1) and the extended temperature range (-40 °C to +125 °C). Confirm that the Q100 designation aligns with your project's requirement for AEC-Q100 Grade 1 automotive qualification. Ensure compatibility with your PCB footprint for the thermal enhanced extremely thin small outline package with side-wettable flanks.

Selection Notes

Select this component when an automotive-grade, single-channel buffer with three-state control is required. The XSON5 package offers a compact form factor suitable for space-constrained designs. The wide supply voltage range and overvoltage tolerance make it suitable for interfacing between different logic families in mixed-voltage systems. Verify that the IOFF feature meets your system's power-down leakage requirements.

Part Context

This part belongs to the 74LVC1G125-Q100 family of bus buffers and line drivers. The 'Q100' suffix indicates qualification to the Automotive Electronics Council standard. The 'GZ' suffix specifically denotes the XSON5 plastic thermal enhanced package with side-wettable flanks. This family provides high noise immunity and CMOS low power consumption characteristics.

Replacement Considerations

The datasheet lists other packages for the same logical function: 74LVC1G125GW-Q100 (TSSOP5), 74LVC1G125GV-Q100 (SC-74A), and 74LVC1G125GM-Q100 (XSON6). These are pin-compatible or functionally equivalent alternatives differing only in physical package dimensions.
