ISL3152EIUZ-T

Overview

The ISL3152EIUZ-T is a half-duplex RS-485 and RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 115Kbps. The device features an IEC 61000-4-2 electrostatic discharge (ESD) protection rating of ±15kV for air discharge and ±8kV for contact discharge. It includes a fail-safe receiver that ensures a high logic state when inputs are open. The component is housed in an 8-lead MSOP package and is rated for operation across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrated ESD protection compliant with IEC 61000-4-2 standards
• Fail-safe receiver design prevents false triggering on open buses
• Slew-rate limited drivers reduce electromagnetic interference

Applications

• Industrial automation control networks
• Building automation systems
• Data acquisition modules

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the manufacturer designation as Renesas Electronics, noting the historical Intersil lineage. Ensure the part number matches the exact 8-MSOP footprint required for the target PCB layout. Validate RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component for applications requiring robust ESD immunity in noisy industrial environments. The 115Kbps speed is suitable for standard Modbus RTU or similar low-to-medium baud rate protocols. Consider the 5V supply requirement against system power rails. The half-duplex architecture limits simultaneous bidirectional communication compared to full-duplex alternatives.

Part Context

This transceiver belongs to the ISL3152E series, designed for reliable serial communication in harsh electrical environments. It serves as a bridge between UART interfaces and differential bus lines. The MSOP package provides a compact solution for space-constrained designs while maintaining thermal performance.
