ISL32458EIBZ-T7A

Overview

The ISL32458EIBZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It features a data rate of 20 Mbps and operates within a supply voltage range of 3V to 5.5V. The device provides 60V overvoltage protection (OVP) on the bus pins and supports a common-mode rejection ratio of 20V. It is housed in an 8-SOIC surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Incorporates 60V overvoltage protection for enhanced bus robustness
• Supports high-speed data transmission up to 20 Mbps
• Features 20V common-mode rejection capability

Applications

• High-speed industrial network communication
• RS-485 bus interface systems
• RS-422 differential line driver applications

Procurement Notes
