ISL54227IRUZ-T

Analog Switches - Special Purpose Overview

The ISL54227IRUZ-T is a USB switch IC designed for high-speed USB 2.0 applications, featuring a dual-pole double-throw (DPST) configuration without voltage protection. It operates on a single supply voltage of 3V or 5V and is housed in a compact 12-UTQFN package measuring 2.2x1.4 mm. The device supports surface mount installation and functions within an operating temperature range of -40°C to +85°C. Key electrical specifications include a maximum on-resistance of 17 ohms, a maximum turn-on time of 160 ns, and a maximum turn-off time of 60 ns.

Analog Switches - Special Purpose Feature Summary

• Supports High-Speed USB 2.0 signaling with DPST topology
• Compact 12-lead ultra-thin QFN package for space-constrained designs
• Operates from standard 3V or 5V single power supplies

Analog Switches - Special Purpose Applications

• USB 2.0 peripheral switching
• Portable electronic devices requiring signal multiplexing
• Consumer electronics with limited board space

Analog Switches - Special Purpose Procurement Notes

Verify component status carefully as the ISL54227IRUZ-T is listed as obsolete by the manufacturer. Sourcing may be restricted or unavailable through primary distributors like Mouser. Engineers should confirm availability through secondary markets or authorized surplus channels before finalizing design implementations to avoid supply chain disruptions.

Analog Switches - Special Purpose Selection Notes

Select this component only if legacy compatibility with the specific 17-ohm on-resistance and 160ns timing parameters is required. Due to its obsolete status, alternative modern equivalents from the same family or competitors should be evaluated for long-term production viability. Ensure the 12-UTQFN footprint matches existing PCB layouts if replacing older designs.

Analog Switches - Special Purpose Part Context

This part belongs to the Renesas Intersil analog switch portfolio, specifically tailored for USB interface management. It complements other multiplexer solutions like the ISL54214 series but offers a distinct DPST configuration optimized for differential data line switching rather than multi-port audio or UART routing.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the component's obsolete status. Designers must consult official replacement guides or contact Renesas sales directly for qualified alternatives.
