ISL3152EIBZ-T7

Overview

The ISL3152EIBZ-T7 is a half-duplex RS-485/RS-422 differential transceiver from the ISL315xE family, manufactured by Renesas Electronics. It operates on a single 4.5V to 5.5V supply and supports data rates up to 115kbps. The device features high output voltage (3.1V typ into 54Ω) for noise immunity and ±16.5kV IEC61000-4-2 ESD protection on bus pins. It provides full fail-safe outputs, hot-plug capability, and ultra-low shutdown current of 70nA. Packaged in an 8-pin SOIC-Narrow with a -40°C to +85°C operating temperature range.

Feature Summary

• High ESD Protection: Withstands ±16.5kV IEC61000-4-2 electrostatic discharge strikes without latch-up on bus I/O pins.
• High Noise Immunity: Delivers typical 3.1V output voltage into a 54Ω load, enabling long bus segments or multiple terminations.
• Low Bus Loading: Constitutes a true 1/8 unit load with less than 125μA bus input current, supporting up to 512 transceivers.
• Fail-Safe Design: Receiver outputs default to a high logic state when bus inputs are open or shorted.

Applications

• Industrial automation networks requiring robust communication over long distances
• Building automation systems utilizing RS-485 multi-drop configurations
• Metering applications needing high ESD tolerance and low standby power

Procurement Notes

Verify the specific suffix T7 indicates cut tape or MouseReel packaging rather than standard reel quantities. Confirm RoHS compliance status and lead-free plating specifications against the latest manufacturer datasheet. Ensure the ordering part number matches the required package type and temperature grade for your assembly process.

Selection Notes

Select this component for half-duplex RS-485/RS-422 applications requiring 115kbps speed. It is suitable where high ESD immunity and fail-safe operation are critical. Compare against ISL3155E or ISL3153E if higher data rates like 1Mbps or full-duplex functionality are needed instead.

Part Context

This part belongs to the ISL315xE series of 5V powered differential transceivers. The series includes variants supporting different data rates (115kbps, 1Mbps, 20Mbps) and duplex modes. The ISL3152E specifically targets standard speed applications with enhanced ruggedness and low power consumption characteristics.

Replacement Considerations

ISL3152EIUZ offers the same electrical performance in an 8-MSOP package. ISL3152EIBZ-T7A is the active replacement for older ISL3152EIBZ-T7 inventory. Verify pinout compatibility and thermal requirements when substituting between SOIC-Narrow and MSOP packages.
