ISL32452EIUZ-T

Overview

The ISL32452EIUZ-T is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.3 V to 5 V and supports data rates up to 250 kb/s. The device features 60 V overvoltage protection on the bus pins and a common-mode rejection ratio of 20 V. It is housed in an MSOP-8 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C. The typical operating supply current is 4.5 mA, and it includes a shutdown mode for power reduction.

Feature Summary

• Integrated 60 V overvoltage protection on differential bus pins to safeguard against electrical faults.
• High common-mode rejection capability ensuring reliable signal integrity in noisy environments.
• Dedicated shutdown pin enables low-power operation by disabling drivers and receivers.

Applications

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

Procurement Notes

Verify the specific suffix T indicates tape-and-reel packaging when sourcing components. Confirm that the MSOP-8 package dimensions align with the target PCB footprint requirements. Ensure the selected variant meets the required thermal management specifications for the intended enclosure environment.

Selection Notes

Select this component for applications requiring robust fault protection on RS-485 buses. The 60 V OVP rating distinguishes it from standard transceivers lacking such protection. Verify compatibility with the system's logic voltage levels, as the device supports both 3.3 V and 5 V supplies.

Part Context

This part belongs to the ISL32452E series of RS-485 interface ICs. It shares functional similarities with other half-duplex transceivers but is specifically characterized by its enhanced overvoltage protection capabilities. The EIUZ suffix denotes the MSOP-8 package configuration used in compact electronic designs.

Replacement Considerations

ISL32452EIUZ is a non-tape equivalent. ISL32455EIUZ offers higher speed but similar protection. Verify pinout compatibility before substitution.
