73S8009R-IL/F

Overview

The 73S8009R-IL/F is a smart card reader and writer power management integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It is housed in a 28-SOIC package and designed for specialized power management applications involving smart card interfaces. The component functions as a level shifter to facilitate communication between the host system and smart cards, ensuring reliable data transfer in compliant environments.

Feature Summary

• Integrates smart card interface functionality with power management capabilities
• Provides level shifting for smart card communication signals
• Designed for use in smart card reader and writer devices

Applications

• Smart card readers
• Smart card writers
• ISO7816-compliant interface systems

Procurement Notes

Verify the exact manufacturer designation, as listings may reference Analog Devices or Maxim Integrated interchangeably due to corporate history. Confirm the 28-SOIC package type matches your PCB footprint requirements. Ensure the specific suffix corresponds to the intended tape-and-reel or tube packaging configuration if applicable. Cross-reference the datasheet version to confirm current electrical specifications and pinout definitions before finalizing procurement.

Selection Notes

Select this component when a combined power management and smart card interface solution is required in a compact surface-mount package. The 28-SOIC form factor offers a balance of pin count and board space efficiency. Consider the operating temperature range and supply voltage requirements against your system's environmental constraints. This part is suitable for applications needing dedicated smart card level shifting without external discrete components.

Part Context

This device belongs to the family of smart card interface ICs from Analog Devices/Maxim Integrated. It complements other variants like the 73S8009C-32IM/F, which utilizes a different package format. The series supports various smart card standards and provides essential signal conditioning for secure identification and transaction processing in embedded systems.

Replacement Considerations

The 73S8009C-32IM/F serves as a functional alternative within the same product family, offering similar smart card interface capabilities but packaged in a 32-VFQFN format instead of the 28-SOIC. Designers must account for the physical footprint differences and potential pinout variations when substituting this part.
