74LVC1G125FX4-7

Overview

The Diodes Incorporated 74LVC1G125FX4-7 is a single non-inverting buffer and bus driver featuring a three-state output. 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 capability of ±24mA at 3.3V and includes IOFF circuitry to support partial power-down applications by disabling outputs to prevent damaging backflow current. It is housed in the X2-DFN1409-6 package.

Feature Summary

• Single non-inverting buffer with three-state output functionality
• IOFF circuitry enables safe partial power-down mode operation
• Inputs accept voltages up to 5.5V for mixed-voltage compatibility
• ESD protection exceeds 2000-V Human Body Model standards

Applications

• Voltage level shifting between different logic families
• General purpose logic signal buffering
• Power down signal isolation in mixed-voltage systems

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 manufacturing lot requirements. Ensure design layouts adhere to the recommended pad dimensions provided in the official package outline documentation to maintain thermal and electrical integrity.

Selection Notes

Select this component when a compact chip-scale solution is required for single-channel buffering. The wide operating voltage range supports diverse system architectures. Verify that the input transition rates align with the specified limits for the target supply voltage to ensure proper switching characteristics and avoid undefined states during operation.

Part Context

This part belongs to the 74LVC1G125 series of single bus buffers with three-state outputs manufactured by Diodes Incorporated. The FX4 ordering suffix specifically identifies the X2-DFN1409-6 package variant, which serves as a chip-scale alternative within the broader family of available packages including SOT and other DFN configurations.

Replacement Considerations

Direct substitutes include the 74LVC1G125FW4-7 and 74LVC1G125FZ4-7 from Diodes Incorporated, which share identical electrical specifications but utilize different package footprints.
