74LVC1G126GV-Q100H

Overview

The Nexperia 74LVC1G126GV-Q100H is a single non-inverting bus buffer and line driver with three-state outputs, housed in a SC-74A (SOT753) plastic surface-mounted package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry to prevent backflow current during partial power-down states. It provides ±24 mA output drive capability at 3.0 V and complies with AEC-Q100 Grade 1 standards.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• IOFF circuitry enables safe partial power-down mode operation
• Schmitt-trigger inputs provide tolerance for slow input rise and fall times
• Direct interface compatibility with TTL logic levels

Applications

• Mixed 3.3 V and 5 V system environments
• Partial power-down applications requiring isolation
• Automotive electronic systems

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74A package configuration required for your design. Confirm that the Q100 designation aligns with your automotive grade requirements. Ensure the component status remains active before finalizing procurement plans. Cross-reference the marking code V26 for physical identification on the device body.

Selection Notes

Select this component when a single-channel buffer with high noise immunity is required in space-constrained automotive designs. The SC-74A package offers a compact footprint suitable for dense PCB layouts. Consider the IOFF feature if the application involves systems where downstream devices may remain powered while this buffer is unpowered.

Part Context

This part belongs to the 74LVC1G126-Q100 family of single bus buffers. Other variants in this series include the GW version in TSSOP5 and the GZ version in XSON5 packages. All variants share identical electrical characteristics and functionality, differing only in physical package dimensions and pin configurations.

Replacement Considerations

The 74LVC1G126GW-Q100H and 74LVC1G126GZ-Q100H are functional equivalents within the same family. Substitution requires verifying package compatibility with the existing PCB footprint, as the SC-74A differs physically from TSSOP5 and XSON5.
