ISL32172EFVZ

Overview

The ISL32172EFVZ is a quad RS-422 driver integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V, supporting standard 3.3 V and 5 V logic levels. The device delivers data transmission rates up to 32 Mb/s with four independent drivers. It features robust electrostatic discharge protection rated at 15 kV according to the Human Body Model. The component is designed for surface-mount installation in a 16-pin Thin Shrink Small Outline Package (TSSOP). It functions reliably across an extended industrial temperature range from -40°C to +125°C while maintaining a low operating supply current of 800 µA.

Feature Summary

• Provides four independent differential drivers compliant with RS-422 standards for reliable serial communication.
• Integrates high-level electrostatic discharge protection to safeguard against transient voltage events.
• Supports high-speed data transmission capabilities suitable for demanding industrial environments.

Applications

• Industrial control systems requiring robust serial communication interfaces
• Factory automation equipment utilizing RS-422 networking protocols
• Data acquisition modules operating in electrically noisy environments

Procurement Notes

Verify the specific package variant and suffix codes against official Renesas documentation before procurement. Confirm that the TSSOP-16 footprint matches the target PCB design constraints. Check for moisture sensitivity level requirements during storage and handling procedures. Ensure compatibility with the intended operating voltage and temperature specifications for the final application environment.

Selection Notes

Select this component when a quad RS-422 driver configuration is required without integrated receivers. Consider the 15 kV ESD rating for applications exposed to static discharge risks. Evaluate the 32 Mb/s data rate capability against system bandwidth requirements. Verify that the 16-pin TSSOP package dimensions fit within the available board space constraints.

Part Context

This part belongs to the ISL32172E series of interface integrated circuits. It serves as a dedicated transmitter solution within the broader portfolio of RS-422 communication components offered by Renesas. The series is engineered for high reliability in industrial settings where signal integrity and noise immunity are critical performance factors.

Replacement Considerations

Consult official Renesas cross-reference documents for verified substitute part numbers. Ensure any replacement maintains identical pinout configurations and electrical characteristics. Verify package compatibility to avoid mechanical integration issues during manufacturing processes.
