The ISL32275EIBZ-T is a ±20kV ESD Protected, 3.0V to 5.5V, Low Power, High Speed, Full Fail-Safe, RS-485/RS-422 Transceiver from Intersil. It's designed for robust communication in harsh environments. This transceiver is suitable for bidirectional data communication on balanced transmission lines. The "EIBZ" and "T" designate the package type, operating temperature range and tape and reel packaging, respectively.

Applications

• Industrial networks
• Process control systems
• Building automation
• Motor control
• Security systems

Features

• ±20kV HBM ESD protection on RS-485 I/O pins
• Single 3.0V to 5.5V supply
• High data rates up to 20Mbps
• Full Fail-Safe (open, short, terminated) RS-485 receiver
• Low quiescent current
• Half-duplex operation
• Thermal overload protection
• Current limiting for driver outputs

Benefits

• Robust communication: Provides reliable data transmission in harsh environments.
• High ESD protection: Protects the transceiver from damage due to electrostatic discharge.
• High data rates: Supports fast data transfer speeds.
• Fail-safe operation: Ensures that the receiver output is in a defined state when the inputs are floating, shorted, or terminated but idle.
• Low power consumption: Minimizes energy consumption.

Additional Details

The ISL32275EIBZ-T is designed to meet the requirements of the RS-485 and RS-422 standards. It features integrated protection circuitry to withstand high voltage electrostatic discharges. The full fail-safe receiver ensures a known output state when the bus is idle or faulty. The device is available in a small outline package (SOIC) or other surface-mount packages. Proper termination of the transmission line is crucial for reliable operation at high data rates. Refer to the Intersil datasheet for detailed specifications, application circuits, and layout recommendations. The ISL32275 series offers excellent performance and reliability for industrial communication applications. The half-duplex configuration means that data can only be transmitted or received at any given time, not both simultaneously.
