ISL3158EIBZ-T7A

Overview

The ISL3158EIBZ-T7A is a single half-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data transmission rates up to 20 Mb/s. The device features an industrial operating temperature range from -40°C to +85°C and is housed in an 8-pin SOIC package. Key electrical characteristics include a shutdown current of 0.07 µA, high ESD protection compliant with IEC 61000 standards, and support for up to 256 devices on the bus.

Feature Summary

• Integrated high electrostatic discharge (ESD) protection meeting IEC 61000 requirements for robust signal integrity.
• Low power consumption capability with a dedicated shutdown mode minimizing standby current draw.
• Supports hot-plug operations without causing damage to the transceiver or system bus.

Applications

• Industrial automation networks requiring reliable RS-485 communication.
• Building automation systems utilizing half-duplex data transmission.
• Metering infrastructure for utility data collection.

Procurement Notes

Verify the specific ordering suffix T7A to confirm reel packaging and ensure compliance with RoHS directives. Confirm moisture sensitivity level classification prior to soldering to prevent package damage during assembly processes.

Selection Notes

Select this component when a single driver and receiver are sufficient for half-duplex applications. Ensure the design requires operation at 5V logic levels and benefits from integrated ESD protection rather than external components.

Part Context

This part belongs to the ISL315xE series of RS-422/RS-485 interface ICs. It shares the same core architecture as variants like the ISL3152E and ISL3155E, differing primarily in maximum data rate specifications and specific pinout configurations.

Replacement Considerations

Direct functional substitutes within the same family include the ISL3152EIBZ-T7A and ISL3155EIBZ-T7A. Verify that the alternative part's data rate and voltage specifications align with the original circuit requirements before substitution.
