ISL32274EFVZ

Overview

The ISL32274EFVZ is a single-driver RS-422 interface integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device achieves data transmission rates up to 10 Mb/s with a quiescent power consumption of 800 uA. It features robust electrostatic discharge protection rated at ±15 kV according to IEC standards. The component is housed in a 16-lead TSSOP package and is designed for reliable operation across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides high-speed differential signaling capability for RS-422 communication protocols.
• Integrates enhanced ESD protection to safeguard against electrical stress events.
• Optimized for low-power applications through reduced quiescent current consumption.

Applications

• Industrial automation control systems requiring robust serial communication.
• Building automation networks utilizing RS-422 bus topologies.
• Test and measurement equipment interfaces demanding high noise immunity.

Procurement Notes

Verify the specific suffix 'FVZ' to confirm the TSSOP-16 package variant and anneal processing status. Confirm RoHS compliance details directly with the manufacturer or authorized distributors, as regulatory status may vary by production batch. Ensure the sourcing channel provides valid traceability documentation for this discontinued series component.

Selection Notes

Select this component when a single driver configuration is required for RS-422 networks. It is suitable for designs needing 10 Mb/s throughput with strict power constraints. Consider the TSSOP-16 footprint compatibility during PCB layout. Verify that the system environment remains within the specified -40°C to +125°C operating temperature limits.

Part Context

This part belongs to the ISL3227xE family of RS-422 drivers. It shares core specifications with variants like the ISL32274EFBZ but differs in packaging. The family is characterized by high ESD tolerance and low power consumption. Note that this specific model may be subject to end-of-life status, requiring careful lifecycle management for long-term production planning.

Replacement Considerations

The ISL32274EFBZ serves as a direct pin-compatible alternative offering identical electrical performance in a SOIC-16 package. Designers must adjust the PCB land pattern to accommodate the different physical dimensions between TSSOP and SOIC packages while maintaining signal integrity.
