ISL32498EIUZ-T7A

Drivers, Receivers, Transceivers Overview

The ISL32498EIUZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It features one driver and one receiver within an 8-pin MSOP package. The device supports data rates up to 15 Mbps and operates on a single 5V supply voltage. It provides ±40V overvoltage protection on the bus pins and withstands ±15kV ESD strikes per IEC 61000-4-2 standards. The component functions reliably across an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±40V fault protection on differential bus lines to safeguard against electrical overstress
• High-speed data transmission capability supporting rates up to 15 Mbps for efficient communication
• Robust electrostatic discharge immunity rated at ±15kV (air discharge) and ±8kV (contact discharge)
• Shutdown mode functionality designed to minimize power consumption during idle periods

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring robust RS-485 communication
• Building automation systems utilizing high-speed data transfer
• Metering infrastructure with exposure to harsh electrical environments
• Factory equipment interfaces demanding high ESD tolerance

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T7A corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-MSOP package dimensions align with the target PCB footprint. Ensure the 5V supply voltage requirement matches the system design constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a half-duplex interface requires 15 Mbps throughput and significant bus protection. Compare against lower-speed variants if bandwidth requirements are less than 15 Mbps. Verify that the 5V operating voltage is compatible with the host logic levels. Consider the thermal performance within the MSOP package for enclosed industrial enclosures.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32498E series, which focuses on high-speed serial communication in noisy environments. The series differentiates itself through superior overvoltage protection compared to standard transceivers. It serves as a critical link in multi-drop networks where signal integrity and hardware durability are paramount.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other Renesas ISL32498 variants with different packaging options such as tubes or cut tape. Cross-brand equivalents must match the 15 Mbps speed, 5V supply, and ±40V protection specifications while maintaining pin compatibility.
