ISL32437EIBZ-T7A

Overview

The ISL32437EIBZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 3V to 5.5V supply and supports data rates up to 250kbps. The device features ±15V common-mode voltage range and ±40V fault protection on the bus pins. It is housed in an 8-MSOP package with a width of 3.00mm. The component functions within an operating temperature range of -40°C to +85°C and includes a shutdown mode for power reduction.

Feature Summary

• Integrated ±40V overvoltage protection on transmit and receive pins to safeguard against bus faults.
• Full fail-safe receiver design ensures a high logic output state when inputs are floating or shorted.
• Supports standard RS-485 communication protocols with ±15V common-mode capability.

Applications

• Industrial automation control networks
• Building automation systems
• Metering infrastructure

Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official datasheets as manufacturing processes may evolve. Check for End-of-Life notices or Product Change Notifications regarding material or assembly updates before finalizing procurement plans.

Selection Notes

Select this component for applications requiring compact surface-mount solutions with robust fault protection. Ensure the system voltage aligns with the 3V to 5.5V operational range. Verify that the 250kbps data rate meets the network requirements, as higher-speed variants exist within the family.

Part Context

This part belongs to the ISL3243xE series of fault-protected transceivers. It shares functional similarities with other members like the ISL32432EIBZ-T7A but differs in duplexing capabilities. The MSOP package distinguishes it from SOIC-based counterparts in the same product line.

Replacement Considerations

ISL32432EIUZ serves as a parameter-equivalent alternative within the same manufacturer portfolio. Verify pin compatibility and package dimensions before substitution. Other family members may offer different speed or protection ratings.
