ISL54227IRUZ-T7A

Analog Switches - Special Purpose Overview

The ISL54227IRUZ-T7A is a high-speed USB 2.0 dual-pole double-throw (DPST) switch integrated circuit manufactured by Renesas Electronics Corporation. It features a single-channel configuration with a maximum on-resistance of 17 ohms and operates within a supply voltage range of 3V to 5V. The device supports a maximum operating frequency of 480 Mbps for USB 2.0 High-Speed data transmission. It is housed in a compact 4-pin package suitable for surface-mount applications.

Analog Switches - Special Purpose Feature Summary

• Supports USB 2.0 High-Speed data rates up to 480 Mbps
• Low on-resistance of 17 ohms for minimal signal loss
• Operates from a single 3V or 5V power supply
• Compact 4-pin packaging for space-constrained designs

Analog Switches - Special Purpose Applications

• USB hub circuits requiring signal switching
• Portable electronic devices with limited board space
• Computer peripherals utilizing USB connectivity
• Consumer electronics with USB interface requirements

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'T7A' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Check for any recent Product Change Notices (PCN) regarding labeling or manufacturing site updates. Ensure compatibility with the target PCB footprint before ordering, as package dimensions are critical for surface-mount assembly.

Analog Switches - Special Purpose Selection Notes

Select this component when a low-profile, single-channel USB switch is required for high-speed data lines. Compare the 17-ohm on-resistance against system impedance requirements to ensure signal integrity. Verify that the 3V to 5V operating voltage aligns with the host system's power rails. Consider the 4-pin form factor for tight spatial constraints compared to larger multiplexer options.

Analog Switches - Special Purpose Part Context

This part belongs to the ISL5422x series of USB switches from Renesas. It shares functional similarities with other members like the ISL54224 but differs in channel count and pinout. The series is designed for portable applications where size and power consumption are primary design drivers. It complements Renesas' broader portfolio of analog and mixed-signal interface solutions.

Analog Switches - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official replacement guide or distributor cross-reference tools for verified alternatives. Ensure any substitute matches the 4-pin package and 17-ohm resistance specification.
