ISL3153EIUZ

Overview

The ISL3153EIUZ is a single RS-485 transceiver manufactured by Renesas Electronics Corporation, belonging to the ISL3153E series. It operates with a fixed supply voltage of 5 V and supports data rates up to 1 Mb/s. The device features one driver and one receiver with differential output types. It functions within an operating temperature range from -40 °C to +85 °C. The component is housed in a 10-lead MSOP package designed for surface mount technology.

Feature Summary

• IEC 61000-4-2 ESD protection rated at ±15 kV for air discharge and ±8 kV for contact discharge on bus pins
• High-voltage differential output capability providing robust signal transmission over long cable runs
• Integrated failsafe receiver ensures a high logic state output when inputs are open or disconnected

Applications

• Industrial automation control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 multi-drop configurations
• Data acquisition modules interfacing with remote sensors

Procurement Notes

Verify the specific suffix EIUZ corresponds to the MSOP-10 package and industrial temperature grade during sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a single half-duplex RS-485 channel with integrated ESD protection. It is suitable for systems operating strictly at 5 V. Consider alternative packages if space constraints differ from the MSOP-10 footprint. Verify that the 1 Mb/s speed meets system timing requirements.

Part Context

This part belongs to the ISL3153E family of RS-485 interface ICs produced by Renesas Electronics. The series focuses on providing robust communication interfaces with built-in protection mechanisms. The ISL3153EIUZ specifically denotes the version packaged in MSOP-10 format intended for industrial environments.

Replacement Considerations

Direct substitutes include other single RS-485 transceivers with similar 5 V operation and ESD ratings. Verify pin compatibility and electrical specifications against datasheets before substitution.
