ISL54222AIUZ-T

Analog Switches - Special Purpose Overview

The ISL54222AIUZ-T is a high-speed USB 2.0 switch IC manufactured by Renesas Electronics Corporation, formerly Intersil. It features a dual single-pole double-throw (DPST) configuration designed for differential data line switching. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports standard 3 V and 5 V logic levels. Key electrical parameters include a maximum on-resistance of 16 Ohms, a maximum bandwidth of 790 MHz, a maximum turn-on time of 160 ns, and a maximum turn-off time of 60 ns. It functions reliably across an industrial temperature range from -40 °C to +85 °C and is housed in an 8-lead PQFP package.

Analog Switches - Special Purpose Feature Summary

• Dual DPST architecture for independent control of differential signal pairs
• High-speed signal integrity with 790 MHz bandwidth supporting USB 2.0 specifications
• Low power consumption suitable for battery-operated portable devices

Analog Switches - Special Purpose Applications

• USB hub implementations requiring signal routing
• Portable computing devices such as laptops and tablets
• Peripheral connection management systems

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check current lifecycle status as discontinuance notifications may apply to legacy Intersil products. Ensure packaging format matches design requirements.

Analog Switches - Special Purpose Selection Notes

Select this component when dual-channel differential switching is required for USB 2.0 interfaces. Compare on-resistance and bandwidth against alternative switches if signal distortion is critical. Verify package compatibility with PCB layout constraints. Consider thermal performance within the specified operating temperature range.

Analog Switches - Special Purpose Part Context

This part belongs to the ISL5422x series of high-speed analog switches. It shares functional similarities with other models in the family but offers specific pinout and performance characteristics tailored for USB applications. The product originates from the Intersil portfolio acquired by Renesas Electronics.

Analog Switches - Special Purpose Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Evaluate alternatives based on identical pin configurations and electrical specifications. Ensure substitute components meet the same USB 2.0 signaling requirements.
