ISL32457EIUZ-T

Drivers, Receivers, Transceivers Overview

The ISL32457EIUZ-T is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 1 Mbps. The device features 60V overvoltage protection (OVP) on the bus pins and provides 20V common-mode rejection capability. It is housed in an MSOP-8 surface-mount package and functions across an industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 60V overvoltage protection for robust bus pin safety
• High common-mode rejection ratio supporting noisy environments
• Low power consumption with dedicated shutdown mode

Drivers, Receivers, Transceivers Applications

• Industrial communication networks requiring RS-485 connectivity
• Building automation systems utilizing RS-422 protocols
• Data acquisition modules in harsh electrical environments

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels, as the part number indicates end-of-life status. Confirm RoHS compliance details via official datasheets before integration. Ensure packaging specifications match production requirements, noting variations between reel and cut tape formats available in legacy stock.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-voltage tolerance is critical for bus line protection. The MSOP-8 package suits space-constrained designs requiring surface mount technology. Verify that the 1 Mbps speed meets system timing requirements and that the 3V to 5.5V supply range aligns with the target platform's power architecture.

Drivers, Receivers, Transceivers Part Context

This transceiver belongs to the ISL3245xE family of protected interface devices. It shares functional similarities with other models in the series but is distinguished by its specific MSOP-8 packaging and thermal characteristics. The product line focuses on providing durable communication interfaces for industrial applications where standard components might fail due to electrical stress.

Drivers, Receivers, Transceivers Replacement Considerations

The ISL32457EIBZ serves as a pin-compatible alternative in the SOIC-8 package. Engineers should verify package dimensions and thermal performance differences when substituting. Other members of the ISL3245xE family may offer similar electrical characteristics but require careful review of pinout and packaging constraints.
