ISL54227IRTZ-T

Analog Switches - Special Purpose Overview

The ISL54227IRTZ-T is a high-speed USB 2.0 switch IC manufactured by Renesas Electronics Corporation, formerly Intersil. It features a single double-pole single-throw (DPST) configuration housed in a compact TDFN-10 package. The device supports dual supply voltages of 3 V and 5 V, with an operating range from 2.7 V to 5.25 V. Key electrical parameters include a maximum on-resistance of 17 Ohms, a bandwidth of 790 MHz, and a typical quiescent current of 35 uA. Switching performance is characterized by a maximum turn-on time of 160 ns and a maximum turn-off time of 60 ns. It operates within a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• High-speed signal integrity optimized for USB 2.0 compliance
• Low power consumption suitable for battery-operated devices
• Compact surface-mount packaging for space-constrained designs

Analog Switches - Special Purpose Applications

• Portable computing devices requiring USB port expansion
• Mobile phones and tablets for peripheral connectivity management
• Digital cameras and camcorders for accessory switching

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeiting risks. Confirm RoHS compliance status via official datasheets before integration. Check for end-of-life notifications as the product may be subject to discontinuation. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during assembly.

Analog Switches - Special Purpose Selection Notes

Select this component when a single DPST switch is required for USB 2.0 data lines. Compare against ISL54226 if an 8-pin package is preferred, noting the pinout differences. Verify that the 17 Ohm on-resistance meets the voltage drop requirements of the specific application. Ensure the TDFN-10 footprint aligns with the PCB layout constraints.

Analog Switches - Special Purpose Part Context

This part belongs to the ISL5422x series of high-speed USB switches. It shares functional similarities with the ISL54226 but differs in package type and pin configuration. The series is designed for portable electronics where low power and small size are critical. It complements other Renesas analog switches used in signal routing applications.

Analog Switches - Special Purpose Replacement Considerations

The ISL54226IRTZ-T is a related variant offering similar electrical performance in an 8-pin TDFN package. Pin compatibility must be verified before substitution due to the difference in package count. No direct pin-for-pin replacements are confirmed in public documentation.
