TXS02324RUKR

Specialized Overview

The TXS02324RUKR is a dual-supply 2:1 SIM card multiplexer and translator integrated circuit manufactured by Texas Instruments. It features slot-dedicated dual low-dropout regulators (LDOs) for independent power management of two SIM slots. The device operates within a supply voltage range of 1.7 V to 3.6 V, supporting various logic levels. Key electrical parameters include a propagation delay of 5 ns or 7 ns depending on configuration, and an operating temperature range from -40°C to +85°C. It is housed in a 20-pin WQFN package with exposed pad, designed for surface-mount installation.

Specialized Feature Summary

• Integrates dedicated dual LDOs for independent power regulation of separate SIM card slots
• Functions as a 2:1 multiplexer and voltage level translator for SIM interface signals
• Supports dual-supply operation to accommodate different voltage domains between host and SIM cards

Specialized Applications

• Smart card interface circuits in mobile handsets
• SIM card slot selection and translation in portable electronic devices
• Dual-SIM phone architectures requiring signal multiplexing and level shifting

Specialized Procurement Notes

Verify the specific suffix 'RUKR' corresponds to the 20-WQFN package and tape-and-reel quantity specified in the official Texas Instruments datasheet. Confirm that the component meets RoHS compliance requirements if mandated by your assembly process. Ensure the ordering information matches the exact pinout and thermal pad specifications required for your PCB layout design.

Specialized Selection Notes

Select this component when designing systems requiring simultaneous management of two SIM slots with distinct voltage requirements. It is suitable for applications needing compact integration of multiplexing, translation, and local power regulation. Consider the 20-WQFN footprint and thermal performance characteristics during the initial hardware architecture phase to ensure adequate heat dissipation.

Specialized Part Context

This part belongs to the TXS series of voltage level shifters and multiplexers from Texas Instruments. It is specifically engineered for smart card applications, distinguishing itself from general-purpose level shifters by including integrated LDOs. The RUKR suffix indicates the specific package type and reel packaging format used for high-volume surface-mount manufacturing.
