ISL32493EIBZ-T

Overview

The ISL32493EIBZ-T is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 10Mbps. The device features ±60V fault protection on the bus pins and provides high electrostatic discharge (ESD) protection rated at ±15kV according to the Human Body Model. It is housed in a 14-lead SOIC package with an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated overvoltage protection for robust operation in electrically noisy industrial environments
• High ESD immunity ensuring signal integrity during exposure to static discharge events
• Wide common-mode voltage range capability for reliable differential communication

Applications

• Industrial control systems requiring robust serial communication
• Building automation networks utilizing RS-485 protocols
• Factory automation equipment interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices, as this specific part number may have limited availability or obsolescence status. Ensure packaging specifications match design requirements.

Selection Notes

Select this component when designing systems requiring 10Mbps RS-485 performance with integrated overvoltage protection. Verify that the 14-lead SOIC package fits the board layout constraints. Ensure the power supply voltage remains within the 3V to 5.5V operational window for correct functionality.

Part Context

This device belongs to the ISL3249xE series of RS-485/RS-422 transceivers from Renesas. It shares architectural similarities with other members of the family but is distinguished by its specific 10Mbps data rate and 14-pin form factor. It serves as a connectivity solution for legacy and modern industrial interfaces.

Replacement Considerations

Direct pin-to-pin replacements include the ISL32493EIBZ without the tape-and-reel suffix. Cross-family alternatives like the ISL32453EIBZ offer similar functionality but operate at lower data rates. Verify electrical parameters before substitution.
