ISL32272EIBZ

Drivers, Receivers, Transceivers Overview

The ISL32272EIBZ is a low-power RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates at a fixed supply voltage of 5 V and supports data rates up to 250 kb/s. The device features one driver and one receiver, housed in an SOIC-8 surface-mount package. It functions within a temperature range of -40 °C to +85 °C and includes a shutdown mode for power conservation.

Drivers, Receivers, Transceivers Feature Summary

• Integrated overvoltage protection on the bus pins to withstand high-voltage faults
• High electrostatic discharge (ESD) immunity rated at ±16.5 kV according to IEC standards
• Low quiescent current with a dedicated shutdown mode to minimize power consumption

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation networks
• Metering infrastructure communication

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity labeling prior to soldering. Ensure storage conditions meet specified humidity limits to prevent package damage during assembly processes.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection and high ESD tolerance in noisy environments. The 5 V supply requirement distinguishes it from 3.3 V variants. Verify that the single driver/receiver configuration meets the specific topology needs of the target serial communication network design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32272E series of RS-485/RS-422 transceivers designed for harsh industrial environments. It shares functional similarities with other members of the family but is distinguished by its specific 5 V operating voltage and integrated overvoltage protection capabilities.
