ISL32452EIBZ-T

Drivers, Receivers, Transceivers Overview

The ISL32452EIBZ-T is a half-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features a single driver and one receiver, housed in an SOIC-8 surface-mount package. It provides extended common-mode rejection of ±20 V and overvoltage protection on bus pins up to ±60 V. The component functions reliably across an operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated fault protection for RS-485 bus pins against overvoltage conditions up to ±60 V
• Extended common-mode range capability supporting voltages up to ±20 V beyond standard requirements
• Built-in fail-safe receiver design ensuring high logic output during input floating or short-circuit states

Drivers, Receivers, Transceivers Applications

• Utility metering and automated meter reading systems
• Industrial process control networks
• Building lighting and environmental control systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent package damage.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection and extended common-mode voltage tolerance. It is suitable for environments with potential bus line overvoltage risks. Verify that the 250 kb/s data rate meets system timing requirements compared to higher-speed alternatives in the series.

Drivers, Receivers, Transceivers Part Context
