ISL32452EIBZ

Overview

The ISL32452EIBZ is a half-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. 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 ±60 V fault protection on driver outputs and provides an extended common-mode range of ±20 V, exceeding standard RS-485 requirements. It is housed in an 8-lead SOIC package with a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated ±60 V overvoltage protection on driver outputs to safeguard against line faults
• Extended ±20 V common-mode voltage range for reliable operation in noisy environments
• ESD protection rated at ±15 kV (HBM) for enhanced robustness

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific suffix 'T13' if ordering tape-and-reel packaging, as the base part number typically denotes tube packaging. Confirm RoHS compliance status through official datasheets or manufacturer notifications. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when half-duplex communication is required with high noise immunity. The ±60 V fault protection makes it suitable for harsh industrial environments where line faults are possible. Compare against the ISL32450EIBZ if full-duplex capability is needed instead.

Part Context

This device belongs to the ISL3245xE family of RS-485/RS-422 transceivers. The family includes variants such as the ISL32450EIBZ (full-duplex) and ISL32458EIBZ (high-speed). All share similar fault protection and power supply characteristics but differ in duplex mode and data rate capabilities.

Replacement Considerations

Publicly confirmed substitutes include the ISL32450EIBZ for full-duplex applications and other members of the ISL3245xE family. Verify pin compatibility and functional equivalence before substitution.
