74LVC1G126FX4-7

Overview

The Diodes Incorporated 74LVC1G126FX4-7 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 provides an output drive current of ±24mA at 3.3V and includes IOFF circuitry to prevent damaging backflow during partial power-down states. It is housed in the X2-DFN1409-6 package.

Feature Summary

• Integrated IOFF circuitry enables safe partial power-down mode by disabling outputs and preventing reverse current flow when powered down.
• Inputs accept voltages up to 5.5V, allowing direct interface with TTL levels and compatibility in mixed-voltage systems.
• Provides high-drive capability with ±24mA output current at 3.3V operation.
• Offers ESD protection exceeding 2000V Human Body Model and 200V Machine Model standards.

Applications

• Voltage level shifting between different logic families
• Power down signal isolation
• General purpose logic applications

Procurement Notes

Verify the FX4 suffix corresponds to the X2-DFN1409-6 package configuration before procurement. Confirm that the specific revision of the datasheet matches the production lot requirements. Ensure the ordering quantity aligns with the standard tape and reel packing specifications provided by the manufacturer.

Selection Notes

Select this component for designs requiring a single-channel buffer with three-state control in space-constrained layouts. The X2-DFN1409-6 package serves as a chip-scale alternative suitable for dense PCB arrangements. Consider the 1.65V to 5.5V operating range when designing for varying supply conditions.

Part Context

This part belongs to the 74LVC1G126 series of single bus buffers manufactured by Diodes Incorporated. The series utilizes LVC logic technology designed for low-voltage CMOS applications. The FX4 suffix specifically designates the X2-DFN1409-6 surface-mount package variant within this product family.

Replacement Considerations

Cross-reference with other manufacturers offering the 74LVC1G126 function in equivalent packages. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength against the original specification sheet.
