FXWA9306MUX

FXWA9306MUX Description

The FXWA9306MUX from onsemi is a bidirectional voltage level translator designed for seamless signal conversion between mixed-voltage systems. Packaged in an 8-pin MSOP and supplied in Tape & Reel (TR), this surface-mount IC supports voltage translation between 1 V to 5.5 V (VCCA) and 1.8 V to 5.5 V (VCCB). With 2 channels per circuit and a single-circuit configuration, it ensures efficient bidirectional data transfer, making it ideal for interfacing low-voltage processors with higher-voltage peripherals. The device is classified under EAR99 and complies with REACH Unaffected environmental standards, though it is marked as Obsolete in production status.

FXWA9306MUX Features

• Bidirectional Voltage Translation: Enables seamless communication between asymmetric voltage domains (1 V–5.5 V and 1.8 V–5.5 V).
• Compact & Reliable: Housed in an 8MSOP package with Moisture Sensitivity Level (MSL) 1, suitable for automated assembly.
• Low Power Consumption: Optimized for energy-efficient designs, reducing system power overhead.
• High-Speed Performance: Supports fast signal switching, critical for I²C, SPI, and UART interfaces.
• Robust Compliance: Meets HTSUS 8542.39.0001 and REACH standards, ensuring environmental and regulatory compatibility.

FXWA9306MUX Applications

• Mixed-Voltage Systems: Bridges communication between 1.8 V MCUs and 5 V sensors/actuators in IoT devices.
• Portable Electronics: Ideal for smartphones, tablets, and wearables requiring voltage adaptation for peripherals.
• Industrial Automation: Facilitates signal translation in PLCs, motor controllers, and sensor networks.
• Consumer Electronics: Used in displays, memory interfaces, and USB-C power delivery circuits.

Conclusion of FXWA9306MUX

The FXWA9306MUX offers a compact, high-performance solution for bidirectional voltage translation, particularly in space-constrained and power-sensitive designs. While obsolete, its wide voltage range, bidirectional capability, and industry compliance make it a reliable choice for legacy systems or applications requiring proven performance. Engineers should evaluate alternative onsemi models for active designs but can leverage this IC for cost-effective mixed-voltage interfacing in existing deployments.
