ISL54401IRZ

Analog Switches - Special Purpose Overview

The ISL54401IRZ is a dual SPDT analog switch IC designed for USB and audio signal routing. It operates on a single supply voltage ranging from 2.7 V to 5.5 V, with a typical operating voltage of 3 V. The device features a maximum on-resistance of 6 Ohms and supports a DC switch current of 150 mA. It is housed in a compact 10-TDFN (3x3 mm) surface-mount package. The component functions within an industrial temperature range of -40°C to +85°C and draws a low quiescent current of 7 µA.

Analog Switches - Special Purpose Feature Summary

• Dual single-pole double-throw (SPDT) configuration for flexible signal path selection
• Low on-resistance suitable for high-fidelity audio and data transmission applications
• Ultra-low power consumption with minimal quiescent current draw
• Compact footprint optimized for space-constrained portable electronic designs

Analog Switches - Special Purpose Applications

• USB peripheral switching and port management
• Audio signal routing in consumer electronics
• Portable device interface protection
• Battery-powered equipment signal multiplexing

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'IRZ' against the manufacturer's legacy documentation to confirm pinout and electrical specifications match the design requirements. Note that Intersil has been acquired by Renesas Electronics; consult official product transfer documents to ensure continued support or identify equivalent modern alternatives if long-term availability is a concern.

Analog Switches - Special Purpose Selection Notes

Select this component when a dual-channel SPDT switch is required for low-voltage digital or analog signals. Ensure the application voltage does not exceed the 5.5 V maximum rating. Consider the 6 Ohm on-resistance impact on signal integrity for high-frequency audio or high-speed data lines compared to lower-resistance alternatives.

Analog Switches - Special Purpose Part Context

The ISL54401IRZ belongs to the Intersil family of specialized analog switches. Originally developed by Intersil, these components are now managed under Renesas Electronics following the corporate acquisition. This part represents a standard solution for integrating multiple signal sources into a single destination in compact embedded systems.

Analog Switches - Special Purpose Replacement Considerations

Consult Renesas Electronics Product Legacy Documents for officially confirmed substitute part numbers. Direct replacements may require verification of package compatibility and electrical parameter alignment.
