ISL54406IRTZ

Analog Switches - Special Purpose Overview

The ISL54406IRTZ is a dual SPST analog switch manufactured by Renesas Electronics Corporation, housed in an 8-pin TDFN package. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a maximum quiescent current of 1 µA. The device features a typical on-resistance of 1.3 Ω and supports continuous DC signal currents up to 250 mA. It provides bidirectional signal transmission with low leakage current and ensures data integrity through ±2 kV HBM ESD protection across all pins.

Analog Switches - Special Purpose Feature Summary

• Dual single-pole single-throw (SPST) configuration for independent channel control
• Ultra-low power consumption suitable for battery-operated applications
• Low on-resistance for minimal signal attenuation
• Bidirectional signal switching capability

Analog Switches - Special Purpose Applications

• Portable audio equipment signal routing
• Battery-powered measurement instruments
• Communication systems interface isolation
• Automotive infotainment signal switching

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'IRTZ' to confirm the tape-and-reel packaging format and lead-free RoHS compliance status. Confirm the manufacturer as Renesas Electronics Corporation or Intersil to ensure component authenticity. Check for obsolescence notices as older Intersil part numbers may have limited availability or require alternative sourcing strategies.

Analog Switches - Special Purpose Selection Notes

Select this component when a dual-channel analog switch with ultra-low standby current is required. Ensure the operating voltage range of 2.7 V to 5.5 V aligns with the system design. Verify that the 1.3 Ω on-resistance meets the signal integrity requirements for the specific application bandwidth and load conditions.

Analog Switches - Special Purpose Part Context

This component belongs to the ISL5440x series of low-power analog switches. It shares functional similarities with other devices in the family but is distinguished by its specific pinout and performance characteristics optimized for portable electronics. The TDFN package allows for compact PCB layout in space-constrained designs.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include the ISL54409IRTZ and ISL54410IRTZ from the same product family. Verify pin compatibility and electrical specifications before substitution. Other manufacturers offer similar dual SPST switches, but parameter matching is essential for direct replacement.
