74LVC1G126W5-7

Overview

The 74LVC1G126W5-7 is a single non-inverting buffer with 3-state output from Diodes Incorporated, housed in an SOT25 package. It operates within a supply voltage range of 1.65V to 5.5V and features inputs tolerant up to 5.5V for mixed-voltage environments. The device supports partial power-down applications via IOFF circuitry to prevent backflow current. Recommended operating conditions specify a free-air temperature range of -40°C to +125°C.

Feature Summary

• Provides high-impedance state control through an active HIGH output enable pin
• Incorporates IOFF circuitry to disable outputs during partial power-down modes
• Features input tolerance up to 5.5V for compatibility in mixed-voltage systems

Applications

• Voltage level shifting between different logic domains
• Power down signal isolation in multi-supply circuits
• General purpose buffering for portable computing devices

Procurement Notes

Verify the specific W5 suffix corresponds to the SOT25 package configuration required for your design. Confirm that the -7 packing suffix matches your automated assembly equipment specifications. Ensure the ordering information aligns with the manufacturer's latest datasheet revision DS32203 Rev. 11-2 to avoid discrepancies in package dimensions or marking codes.

Selection Notes

Select this component when a single-channel buffer with controlled tri-state functionality is required. The LVC family offers low power consumption suitable for battery-operated devices. Consider the SOT25 package size constraints and verify thermal resistance characteristics if operating near maximum temperature limits. Ensure input signals remain within the specified voltage tolerances for reliable operation.

Part Context

This part belongs to the 74LVC1G126 series of single bus buffers. It shares functional similarities with other variants like the SE and Z packages but differs in physical footprint. The W5 designation specifically identifies the SOT25 surface-mount package option within the broader product line manufactured by Diodes Incorporated.

Replacement Considerations

Direct substitutes include the 74LVC1G126SE-7 (SOT353) and 74LVC1G126Z-7 (SOT553). Verify pinout compatibility and package dimensions before substitution. Other manufacturers may offer equivalent logic functions, but electrical characteristics must be cross-referenced against the official datasheet.
