ISL32472EIBZ-T7A

Drivers, Receivers, Transceivers Overview

The ISL32472EIBZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 5 V supply and supports data rates up to 250 kb/s. The device features overvoltage protection (OVP) on the bus pins, allowing tolerance of ±15 V common-mode voltages while powered down or active. It includes an enable pin for shutdown mode with low power consumption of 2.3 mA. The component is housed in an 8-lead SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated overvoltage protection on differential bus pins for robust signal integrity
• Low-power shutdown capability via dedicated enable control
• Compliance with RS-422 and RS-485 communication standards

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring noise immunity
• Building automation systems utilizing RS-485 buses
• Process control instrumentation interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure the SOIC-8 footprint matches the target PCB layout constraints. Validate that the 5 V supply requirement aligns with the system power architecture.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5 V interface is required alongside high-voltage tolerance on the bus lines. It is suitable for designs needing moderate data speeds up to 250 kb/s without complex termination. Compare against lower-speed variants if power consumption is critical, or higher-speed models if bandwidth exceeds 250 kb/s requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3247xE family of protected transceivers from Renesas. These devices are designed for harsh electrical environments where bus line faults may occur. The series provides a balance between protection capabilities and standard serial communication performance for industrial applications.

Drivers, Receivers, Transceivers Replacement Considerations

Check for ISL32475EIBZ-T7A as a related variant, noting differences in data rate specifications. Verify compatibility with direct replacements like the MAX3247E series if pin-out and voltage levels match exactly.
