ISL54222AIRTZ

Analog Switches - Special Purpose Overview

The ISL54222AIRTZ is a high-speed USB 2.0 multiplexer designed for single-supply operation with voltage ranging from 1.8V to 3.3V. It integrates two independent Single Pole/Double Throw (SPDT) switches, functioning as dual 2:1 multiplexers. The device supports data rates up to 480Mbps and features a -3dB bandwidth of 780MHz. It utilizes a break-before-make switching action to ensure signal integrity. The component is available in DFN10, MSOP10, and uTQFN10 packages and operates within a temperature range of -40°C to 85°C.

Analog Switches - Special Purpose Feature Summary

• Supports high-speed USB 2.0 data transmission at 480Mbps
• Integrates two independent SPDT switches for dual channel routing
• Features break-before-make switching action to prevent signal interference

Analog Switches - Special Purpose Applications

• USB hub designs
• Portable electronic devices requiring signal routing
• High-speed data interface protection circuits

Analog Switches - Special Purpose Procurement Notes

Verify the specific package variant (DFN10, MSOP10, or uTQFN10) required for your PCB layout, as the suffix indicates the package type. Confirm that the supply voltage range of 1.8V to 3.3V aligns with your system design. Ensure the operating temperature range of -40°C to 85°C meets your environmental requirements. Check current availability status as some variants may be obsolete.

Analog Switches - Special Purpose Selection Notes

Select this component when dual-channel USB 2.0 signal routing is required within a compact surface-mount footprint. The low on-state resistance of 8 Ohms ensures minimal signal degradation. Consider the break-before-make feature if signal overlap prevention is critical. Verify compatibility with 1.8V to 3.3V logic levels and single-supply constraints.

Analog Switches - Special Purpose Part Context

The ISL54222AIRTZ belongs to Renesas' high-speed analog switch family, specifically optimized for USB applications. It replaces older Intersil designs with improved performance metrics. The device is part of a series offering various packaging options to suit different board space limitations while maintaining consistent electrical characteristics for high-frequency signal handling.

Analog Switches - Special Purpose Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas product line. Verify if newer revisions offer updated packaging or extended temperature ranges. Ensure substitute parts maintain the 480Mbps speed and 1.8V-3.3V operating voltage specifications.
