ISL32272EFBZ-T

Overview

The ISL32272EFBZ-T is a quad RS-422 driver manufactured by Renesas Electronics Corporation, belonging to the ISL32272E series. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 10 Mb/s. The device features four drivers with zero receivers, drawing an operating supply current of 800 uA. It provides ±15 kV ESD protection on bus I/O pins and functions reliably across an extended temperature range from -40 °C to +125 °C. The component is housed in a 16-lead SOIC-Narrow package.

Feature Summary

• Provides robust electrostatic discharge protection rated at ±15 kV for reliable operation in electrically noisy environments.
• Supports high-speed differential signaling with data transmission capabilities up to 10 Mb/s.
• Integrates four independent drivers to facilitate multi-drop communication topologies.
• Operates effectively across industrial and extended temperature ranges without performance degradation.

Applications

• Industrial automation systems requiring robust serial communication interfaces
• Factory equipment and process control networks utilizing RS-422 standards
• Data acquisition systems operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'FBZ' to confirm the SOIC-Narrow-16 package configuration, as other suffixes indicate different physical footprints. Confirm RoHS compliance status through official documentation before integration. Check for End-of-Life notices or production discontinuation announcements from Renesas to ensure long-term supply availability for manufacturing cycles.

Selection Notes

Select this component when a quad-driver RS-422 interface is required without integrated receiver functionality. Ensure the design accommodates the 16-lead narrow SOIC footprint and thermal requirements for the -40 °C to +125 °C operating range. Verify that the system power supply remains stable between 3 V and 5.5 V to maintain signal integrity and proper logic levels.

Part Context

This part belongs to the ISL32272E family of RS-422 interface integrated circuits produced by Renesas Electronics Corporation. The family includes variants with different packaging options such as TSSOP-16 (EFVZ) and SOIC-Narrow-16 (EFBZ). These devices are designed for high-reliability applications requiring strong ESD immunity and wide temperature tolerance.

Replacement Considerations

The ISL32272EFVZ-T serves as a pin-compatible alternative within the same series, differing only in its TSSOP-16 package instead of the SOIC-Narrow-16 form factor. Verify mechanical clearance and board layout compatibility before substituting packages.
