ISL32273EFBZ-T

Drivers, Receivers, Transceivers Overview

The ISL32273EFBZ-T is a quad receiver integrated circuit belonging to the RS-422/RS-485 interface family manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data transmission rates up to 20 Mb/s. The device features four independent receivers housed in a 16-lead Narrow SOIC package with surface mount installation. It provides robust protection against electrostatic discharge, rated at ±15 kV, and functions reliably across an extended temperature range from -40 °C to +125 °C. The typical operating supply current is specified at 5.5 mA.

• Quad differential receiver architecture for high-density bus applications
• High electrostatic discharge immunity on bus I/O pins
• Extended industrial temperature rating for harsh environments

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Building management systems
• Process instrumentation communication links

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure storage conditions adhere to JEDDEC standards to prevent humidity damage before reflow soldering processes are initiated.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple receive channels without integrated drivers. Verify that the narrow SOIC footprint fits the target PCB layout constraints. Ensure the power supply rail remains stable between 3 V and 5.5 V to maintain signal integrity and proper logic threshold operation during all environmental conditions.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3227xE series of RS-422/RS-485 interface devices. It complements driver-only variants like the ISL32272E by providing the receiving functionality necessary for full duplex or half-duplex communication topologies. The series is designed for reliable data exchange in noisy industrial settings.

Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives within the same Renesas interface portfolio. Verify that any substitute maintains the 20 Mb/s speed capability and ±15 kV ESD rating. Ensure the replacement package matches the 16-lead Narrow SOIC dimensions for mechanical fit.
