ISL32272EFBZ

Drivers, Receivers, Transceivers Overview

The ISL32272EFBZ is an RS-422 interface integrated circuit manufactured by Renesas Electronics Corporation, belonging to the ISL32272E series. It functions exclusively as a quad driver with zero receivers, supporting data rates up to 10 Mb/s. The device operates on a supply voltage range of 3 V to 5.5 V, drawing a typical operating supply current of 800 uA. It features robust electrostatic discharge protection rated at +/- 15 kV and is designed for industrial environments with an extended operating temperature range from -40 C to +125 C. The component is housed in a 16-lead Narrow SOIC package.

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications. Validate that the specific suffix denotes the correct narrow SOIC variant required for the footprint.

Drivers, Receivers, Transceivers Selection Notes

Select this part when only transmitter functionality is needed for RS-422 links. Ensure the design accommodates the 16-lead narrow SOIC footprint constraints. Verify that the 10 Mb/s speed meets system timing requirements. Consider thermal management within the specified -40 C to +125 C range during layout planning.

Drivers, Receivers, Transceivers Part Context

This component is part of the ISL32272E family, which focuses on high-reliability RS-422 drivers. The 'FBZ' suffix indicates the specific 16-lead Narrow SOIC packaging configuration. It serves as a dedicated transmitter solution within the broader Renesas interface portfolio, distinct from transceiver models that include receiver circuits.
