ISL3152EIBZ

Overview

The ISL3152EIBZ is a half-duplex RS-485/RS-422 differential 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 high output drive capability with a typical VOD of 3.1V into a 54Ω load, providing robust noise immunity. It incorporates ±16.5kV IEC 61000-4-2 ESD protection on bus pins and withstands ±100V transient overvoltage. The receiver includes full fail-safe outputs for open or shorted inputs. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• High ESD protection rated at ±16.5kV per IEC 61000-4-2 standard without latch-up
• True 1/8 unit load configuration enabling connection of up to 512 transceivers on the bus
• Hot plug capability ensuring driver and receiver outputs remain high-impedance during power transitions
• Full fail-safe design maintains high receiver output when bus inputs are open or shorted

Applications

• Industrial automation networks requiring reliable RS-485 communication
• Building automation systems utilizing RS-422/RS-485 protocols
• Metering applications in utility infrastructure
• Process control systems operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'BZ' corresponds to the SOIC-8 tube packaging variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required package style and temperature grade. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Selection Notes

Select this component for applications requiring 115kbps data rates with high noise immunity. The 1/8 unit load specification allows for extensive bus topologies compared to standard 1/4 unit load devices. Verify that the 4.5V to 5.5V supply range aligns with system power rails. Consider the SOIC-8 package dimensions for PCB layout constraints.

Part Context

This device belongs to the ISL315xE family of 5V powered RS-485/RS-422 transceivers. The family includes both half-duplex and full-duplex variants with varying data rate capabilities. The ISL3152EIBZ specifically addresses the need for ruggedized communication interfaces in industrial settings where ESD events and line faults are common concerns.

Replacement Considerations

Direct functional substitutes within the same family include ISL3152EIUZ (MSOP package) and ISL3152EIBZ-T7A (SOIC-8 tape and reel). Verify package compatibility and moisture sensitivity levels before substitution.
