ISL32374EFVZ

Overview

The ISL32374EFVZ is a quad RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It integrates four drivers and zero receivers, providing unidirectional data transmission capabilities for multi-drop communication networks. The device supports data rates up to 10 Mbps and operates within a supply voltage range of 3 V to 5.5 V. Designed for industrial environments, it functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a 16-TSSOP package with a width of 4.40 mm, facilitating surface-mount installation on printed circuit boards.

Feature Summary

• Supports RS-422 and RS-485 communication protocols for reliable serial data transmission.
• Integrates four independent drivers to enable multi-drop bus configurations.
• Operates effectively in harsh industrial conditions with an extended temperature rating.

Applications

• Industrial automation control systems requiring robust serial communication.
• Multi-drop RS-485 networks for sensor and actuator interfacing.
• Building automation and security system gateways.

Procurement Notes

Verify the current lifecycle status before integration, as availability may be limited due to end-of-life designations. Confirm that the 16-TSSOP footprint matches the target PCB layout. Ensure the 3 V to 5.5 V operating range aligns with the system power supply rails. Validate thermal management requirements for operation at temperatures up to 125°C.

Selection Notes

Select this component when a quad-driver solution is required for RS-485 or RS-425 networks without integrated reception. Consider the 10 Mbps speed limit and 3 V to 5.5 V voltage range against system specifications. Evaluate the 16-TSSOP package constraints for board space. Verify compatibility with existing protocol stacks and bus termination strategies.

Part Context

This transceiver belongs to the Renesas ISL3237x series of high-speed serial interface components. It serves as a driver-only variant within the broader family of mixed driver-receiver devices. The part is designed to replace legacy discrete driver solutions, offering higher integration density and improved signal integrity for standard industrial communication buses.

Replacement Considerations

Check for direct pin-compatible replacements within the Renesas portfolio. Verify if updated revisions offer enhanced ESD protection or lower power consumption. Ensure any substitute maintains the 16-TSSOP package and 10 Mbps data rate capability.
