ISL3153EIBZ-T

Overview

The ISL3153EIBZ-T is a half-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates with a single 5 V supply and supports data rates up to 12 Mb/s. The device features IEC 61000-4-2 ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). It is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• IEC 61000-4-2 compliant electrostatic discharge protection for robust operation in harsh environments
• High-voltage differential output capability designed for long-distance communication on noisy bus lines
• Integrated thermal shutdown circuitry to protect the device during fault conditions

Applications

• Industrial automation control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 bus topologies
• Metering infrastructure including electricity and gas smart meters

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm that the component meets current RoHS directives and lead-free requirements before integration into final assemblies.

Selection Notes

Select this component when high ESD immunity is critical for field-deployed equipment. Ensure the system design accommodates the 5 V supply voltage and matches the 12 Mb/s maximum data rate requirements of the application protocol.

Part Context

This part belongs to the ISL315xE series of ruggedized RS-485 transceivers. It shares core architectural features with other members like the ISL3152E and ISL3155E, differing primarily in pin count and specific interface configurations within the broader product family.

Replacement Considerations

Direct functional substitutes include the ISL3152EIBZ-T and ISL3155EIBZ-T. Verify pin compatibility and package dimensions before substitution to ensure mechanical fit without PCB redesign.
