FXWA9306L8X

Translators, Level Shifters Overview

The FXWA9306L8X is a dual bi-directional I2C-bus and SMBus voltage-level translator manufactured by onsemi. It operates with VCCA from 1.0V to 5.5V and VCCB from 1.8V to 5.5V, supporting Standard-Mode, Fast-Mode, and Fast-Mode Plus protocols. The device features a maximum propagation delay of 1.5ns and includes an enable (OE) input for control. Packaged in an 8-terminal Leadless MicroPak (1.6mm x 1.6mm), it functions within an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides automatic bi-directional voltage translation between A-side and B-side ports without requiring a direction pin.
• Compatible with Standard-Mode, Fast-Mode, and Fast-Mode Plus I2C-bus and SMBus devices.
• Features low on-state resistance to minimize signal distortion during data transmission.
• Includes an OE input that forces all I/O pins into a high-impedance 3-state when driven low.

Translators, Level Shifters Applications

• Mixed-mode I2C-bus applications connecting devices with different supply voltages
• SMBus systems requiring voltage level shifting
• Multi-master I2C bus configurations

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix L8X corresponds to the 8-Lead MicroPak package and tape-and-reel packing method. Confirm the manufacturer part number matches exactly before procurement. Ensure application requirements align with the specified voltage ranges and temperature limits defined in the datasheet.

Translators, Level Shifters Selection Notes

Select this component for designs requiring compact footprint solutions due to the MicroPak package. Ensure the system design accounts for pull-up resistor sizing to limit pass transistor current. Verify that the OE pin logic levels are compatible with the VCCB supply for proper enable functionality.

Translators, Level Shifters Part Context

This device belongs to the FXWA9306 series of dual bi-directional translators. It shares functional characteristics with other variants like the FXWA9306MUX but differs in physical packaging. The series addresses mixed-voltage interface challenges in modern electronic systems.

Translators, Level Shifters Replacement Considerations

FXWA9306MUX serves as a functional alternative within the same series, offering identical electrical performance but utilizing an MSOP package instead of the MicroPak form factor.

Translators, Level Shifters FAQ

Does the FXWA9306L8X require a direction pin for operation?

No, the device provides bi-directional voltage translation automatically without requiring a direction pin.

What is the function of the OE pin?

The OE (Output Enable) input controls the device state; driving it low forces the A0, A1, B0, and B1 pins into a 3-state condition.
