ISL54406IRUZ-T

Analog Switches - Special Purpose Overview

The ISL54406IRUZ-T is a dual single-pole/single-throw (SPST) switch from the ISL54409 series, manufactured by Renesas Electronics. It operates within a supply voltage range of 2.7 V to 5 V and draws a typical operating current of 7 µA. The device features a maximum on-resistance of 2.8 Ohms, with a maximum turn-on time of 5 µs and a maximum turn-off time of 45 ns. It supports a DC switch current of 150 mA and functions reliably across an ambient temperature range of -40 °C to +85 °C. The component is housed in a compact 10-lead µTQFN package measuring 1.8 mm x 1.4 mm.

Analog Switches - Special Purpose Feature Summary

• Provides stereo audio switching with comprehensive click and pop elimination measures for power-up, power-down, and muting events without external timing components.
• Delivers high off-isolation exceeding 110 dB for effective signal muting into low or high impedance loads.
• Ensures instant recovery from muting states even when large DC blocking capacitors are present in the circuit.

Analog Switches - Special Purpose Applications

• Consumer entertainment systems
• MP3 and personal media players
• Cellular and mobile phones
• Audio switching and muting circuits

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix IRUZ against the manufacturer's official datasheet to confirm the package type and tape-and-reel configuration. Confirm RoHS compliance status through the latest documentation. Check for obsolescence notices as distribution availability may vary. Ensure the supplier provides valid traceability for the Renesas brand.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring low distortion audio paths and robust click/pop suppression. Verify that the 2.8 Ohm on-resistance meets the signal integrity requirements for the specific load impedance. Ensure the 2.7 V to 5 V supply range aligns with the system's power architecture. Consider the 10-lead µTQFN footprint for PCB layout constraints.

Analog Switches - Special Purpose Part Context

The ISL54406 belongs to the ISL54409 family of USB and audio switches. This series integrates SPST switches designed for portable electronics. The IRUZ-T designation indicates a specific surface-mount variant in a tiny ultra-thin package, optimized for space-constrained mobile and consumer devices.

Analog Switches - Special Purpose Replacement Considerations

Check for direct pin-compatible substitutes within the ISL54409 family. Verify electrical parameters such as on-resistance and isolation levels against alternative Renesas audio switches. Ensure thermal performance matches the original design specifications.
