ISL32273EIBZ

Overview

The ISL32273EIBZ is a quad receiver integrated circuit designed for RS-422 and RS-485 communication protocols. Manufactured by Renesas Electronics Corporation, this component operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 80 Mbps. It features a 16-SOIC package with a width of 3.90 mm and is rated for an operating temperature range from -40°C to +85°C. The device includes a receiver hysteresis of 30 mV to improve noise immunity. It complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• Provides four independent receivers for differential signal conversion in RS-422 and RS-485 networks.
• Incorporates 30 mV hysteresis on inputs to enhance noise rejection capabilities.
• Supports high-speed data transmission with a maximum rate of 80 Mbps.

Applications

• Industrial control systems requiring robust multi-drop communication.
• Building automation networks utilizing RS-485 bus architectures.
• Data acquisition modules interfacing with remote sensors.

Procurement Notes

Verify the specific suffix 'EIBZ' to confirm the tube packaging format and lead-free status. Ensure the procurement order matches the 16-SOIC physical dimensions required for the target PCB footprint. Confirm that the supplier provides valid RoHS3 compliance documentation consistent with the manufacturer's current specifications.

Selection Notes

Select this component when a design requires only receiving functionality without integrated drivers. Compare the 80 Mbps speed against lower-speed alternatives if bandwidth requirements are modest. Verify that the 3 V to 5.5 V supply range aligns with the system power rails and that the 16-SOIC package fits the available board space constraints.

Part Context

This part belongs to the ISL32x73 family of interface components, which focuses on providing standalone receiver solutions for serial communication buses. It complements driver-only or transceiver variants within the same product line, allowing designers to mix and match components based on specific network topology needs.

Replacement Considerations

Publicly confirmed substitute part numbers include ISL32273EIBZ-T for reel packaging variations. Other family members like ISL32277EIRZ offer similar quad receiver functions but differ in package type and pin count.
