74LVC1G126FW4-7

Overview

The Diodes Incorporated 74LVC1G126FW4-7 is a single non-inverting buffer and bus driver featuring three-state outputs. It operates within a supply voltage range of 1.65V to 5.5V, with inputs tolerant up to 5.5V for mixed-voltage environments. The device incorporates IOFF circuitry to support partial power-down applications by disabling outputs and preventing damaging current backflow when powered down. It is housed in an X2-DFN1010-6 package.

Feature Summary

• Features integrated IOFF circuitry that disables outputs and prevents current backflow during partial power-down conditions.
• Provides three-state output control via the OE pin, entering a high-impedance state when OE is low.
• Inputs accept voltages up to 5.5V, enabling direct interface with TTL levels in mixed-voltage systems.

Applications

• Voltage level shifting
• Power down signal isolation
• General purpose logic

Procurement Notes

Verify the specific ordering suffix FW4 corresponds to the X2-DFN1010-6 package configuration. Confirm RoHS compliance and lead-free status requirements against project specifications. Ensure the -7 packing suffix matches the required tape and reel quantity for manufacturing processes.

Selection Notes

Select this component for designs requiring a single-channel buffer with active-high enable control. The wide operating voltage range supports both low-power and standard logic interfaces. Verify thermal resistance parameters if operating near maximum temperature limits.

Part Context

This part belongs to the 74LVC1G126 series of single buffers with three-state outputs manufactured by Diodes Incorporated. The series offers various package options including SOT and DFN types. The FW4 suffix specifically designates the X2-DFN1010-6 footprint.

Replacement Considerations

Cross-reference with other manufacturers' 74LVC1G126 equivalents such as Nexperia or Texas Instruments variants. Verify pinout compatibility and electrical characteristics before substitution.
