ISL54211IRTZ

Analog Switches - Special Purpose Overview

The ISL54211IRTZ is a dual Single Pole/Double Throw (SPDT) analog switch IC designed for low-voltage applications. It integrates high-speed USB 2.0 data switching with low-distortion audio signal handling in a single package. The device supports USB 2.0 High-Speed signaling at 480Mbps and Full-Speed at 12Mbps. It operates on a single supply voltage ranging from 2.7V to 5.0V. Key electrical parameters include a -3dB bandwidth of 700MHz for the USB switch, THD+N of 0.014% at 1mW into a 32Ω load, and OFF isolation of 95dB between 20Hz and 100kHz. The component is housed in a 10-lead TDFN package measuring 3mm x 3mm.

Analog Switches - Special Purpose Feature Summary

• Combines low distortion audio switching with accurate USB 2.0 High-Speed data signal routing within a single low-voltage device.
• Enables audio signal swings below ground potential when powered by a single supply, facilitating shared connector usage.
• Features specialized click and pop suppression circuitry activated by an enable pin to eliminate noise during power-up or headphone insertion.
• Logic control pins are compatible with 1.8V logic levels when operating within the 2.7V to 3.6V supply range.

Analog Switches - Special Purpose Applications

• Personal media players requiring combined MP3 audio and USB connectivity
• Cellular and mobile phones utilizing common audio/USB ports
• Portable battery-powered devices with integrated headphone jacks

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'IRTZ' against the manufacturer's current datasheet to confirm the exact package type and lead finish specifications. Ensure that the required operating temperature range aligns with the industrial grade limits defined in the official documentation. Cross-reference the RoHS compliance status directly with the latest environmental declaration provided by Renesas Electronics Corporation.

Analog Switches - Special Purpose Selection Notes

Select this component when a design requires simultaneous switching of high-speed USB data lines and sensitive audio signals using a single control interface. It is suitable for systems needing negative signal handling capabilities without requiring dual power supplies. Consider the 10-lead TDFN package constraints regarding thermal dissipation and PCB layout space availability.
