ISL54216IRTZ

Analog Switches - Special Purpose Overview

The ISL54216IRTZ is a dual-channel USB and UART switch IC manufactured by Renesas Electronics. It features two independent SP3T switches with a 3:1 multiplexer configuration, housed in a compact 12-TQFN (3x3 mm) surface-mount package. The device operates on a single supply voltage ranging from 2.7V to 4.6V. Key electrical specifications include a maximum on-resistance of 15 ohms and a -3dB bandwidth of 800MHz. Switching performance is characterized by a maximum turn-on time of 125 ns and a maximum turn-off time of 125 ns. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix and manufacturer lot codes against current Renesas documentation before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any recent product change notices or end-of-life announcements that may affect long-term availability. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring dual independent signal paths with USB 2.0 compatibility. The 15-ohm on-resistance and 800MHz bandwidth are suitable for high-speed digital signals. Consider the 12-TQFN package dimensions for PCB layout constraints. Verify that the 2.7V to 4.6V supply range aligns with the system power architecture.

Analog Switches - Special Purpose Part Context

The ISL54216 belongs to the Renesas USB switch and multiplexer family, originally developed under the Intersil brand prior to acquisition. This series focuses on providing reliable signal routing for portable and industrial applications. The device replaces older discrete switching solutions by integrating multiple channels into a single small-footprint package, simplifying board design and reducing component count.

Analog Switches - Special Purpose Replacement Considerations

Consult official Renesas cross-reference lists for verified substitutes. Generic analog switches may not meet the specific USB 2.0 signaling requirements or the exact pinout configuration. Verify functional equivalence regarding on-resistance, bandwidth, and package dimensions before substitution.
