ISL32273EIVZ-T

Overview

The ISL32273EIVZ-T is a quad receiver integrated circuit from the Renesas ISL32273E series, designed for RS-422 and RS-485 communication interfaces. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data transmission rates up to 20 Mb/s. The device features robust electrostatic discharge (ESD) protection rated at +/-15 kV according to IEC standards. It is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP) with an exposed pad. The component is specified for industrial temperature ranges, functioning reliably between -40°C and +85°C.

Feature Summary

• Provides four independent receivers for high-speed differential signaling
• Ensures signal integrity through fail-safe circuitry under open or shorted bus conditions
• Offers enhanced ESD protection compatible with harsh industrial environments

Applications

• Industrial automation control systems
• Building automation and security networks
• Factory floor sensor interfaces

Procurement Notes

Verify the specific suffix 'IVZ' confirms the TSSOP-16 package variant and reel packaging format. Confirm RoHS compliance status via the manufacturer's current documentation. Ensure the ordering quantity aligns with the standard reel size requirements for surface mount assembly processes.

Selection Notes

Select this component when a quad receiver topology is required for RS-422 or RS-485 buses. It is suitable for designs needing high ESD immunity without external protection components. Consider the 20 Mb/s speed capability against system latency requirements. Verify that the 3.0 V to 5.5 V supply range matches the target logic levels.

Part Context

This part belongs to the ISL3227xE family of interface controllers. It complements driver-only variants like the ISL32272E by providing the receiving end of the communication link. The series is engineered for reliable data transfer in electrically noisy environments common in industrial settings.

Replacement Considerations

Check for direct pin-compatible successors within the Renesas portfolio. Verify if newer generations offer improved power consumption or extended temperature ranges while maintaining the same 16-lead TSSOP footprint.
