ISL32172EIBZ-T

Overview

The ISL32172EIBZ-T is an RS-422 interface integrated circuit manufactured by Renesas Electronics Corporation, belonging to the ISL32172E series. It functions exclusively as a quad driver with zero receivers, designed for high-speed serial communication. The device supports data rates up to 32 Mb/s and operates within a supply voltage range of 3.0 V to 5.5 V. Key electrical parameters include a maximum operating current of 800 uA and robust electrostatic discharge protection rated at ±15 kV. It is housed in a 16-lead SOIC-Narrow package suitable for surface mount technology and is rated for operation between -40°C and +125°C.

Feature Summary

• Provides four independent differential drivers compliant with RS-422 standards for reliable data transmission.
• Features enhanced electrostatic discharge protection capable of withstanding ±15 kV human body model events.
• Supports high-speed data transfer rates up to 32 Mb/s for efficient communication applications.
• Operates reliably across an extended industrial temperature range from -40°C to +125°C.

Applications

• Industrial control systems requiring robust RS-422 communication links.
• Data acquisition networks utilizing high-speed differential signaling.
• Embedded systems operating in environments with significant electromagnetic interference.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints for 16-lead SOIC packages. Review datasheet specifications for thermal management needs under maximum load conditions.

Selection Notes

Select this component when only transmitter functionality is required for RS-422 networks. Consider the 32 Mb/s speed limit against higher-speed alternatives if bandwidth demands exceed specifications. Evaluate the ±15 kV ESD rating against environmental exposure risks. Verify that the 3.0 V to 5.5 V supply range aligns with system power architecture.

Part Context

This part belongs to the ISL32172E family of RS-422 drivers, distinct from transceiver variants like the ISL32173 which include receivers. The 'T' suffix indicates tape and reel packaging, while 'EIBZ' denotes specific lead-free and RoHS-compliant construction. It serves as a specialized driver solution within Renesas's broader interface portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Check for pin-compatible drivers within the same RS-422 category if direct equivalents are required.
