ISL32496EIBZ-T7A

Overview

The ISL32496EIBZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It supports data rates up to 10 Mbps and operates on a single 3V to 5.5V supply. The device features ±15kV HES ESD protection on the bus pins and includes thermal shutdown and short-circuit current limiting for robust operation. It is housed in an 8-MSOP package with an operating temperature range of -40°C to +85°C.

Feature Summary

• High electromagnetic susceptibility (HES) receiver design for reliable communication in noisy environments
• Integrated electrostatic discharge (ESD) protection rated at ±15kV Human Electrostatic Model on I/O lines
• Built-in thermal shutdown circuitry to prevent damage during excessive power dissipation

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify component authenticity through authorized distributors due to high counterfeit risk. Confirm RoHS compliance status as manufacturing processes may evolve. Check for obsolescence notices or lifecycle changes directly from Renesas, as availability varies significantly across regions and timeframes.

Selection Notes

Select this component when high noise immunity is critical for RS-485 links. Ensure the application requires half-duplex communication within the specified voltage range. Verify that the 8-MSOP footprint fits the PCB layout constraints compared to alternative packages like SOIC.

Part Context

This part belongs to the ISL324xx series of high-speed RS-485/RS-422 transceivers. It shares functional similarities with other members of the family but differs in pinout, speed, and specific protection ratings. It serves as a standard interface solution for differential serial communication in industrial settings.

Replacement Considerations

ISL32496EIBZ is a non-tape reel variant of the same device. ISL32496EIUZ offers the same electrical specifications in a 10-MSOP package. Verify pin compatibility before substituting with different package types.
