The ISL31472EIBZ-T7A is a ±15kV ESD protected, fractional unit load, low power, high speed differential transceiver that meets both the RS-485 and RS-422 standards for balanced communication. This transceiver operates from a single 3.0V to 5.5V supply and features a low quiescent current. It incorporates one driver and one receiver in a half-duplex configuration.

Applications

• Industrial networks
• Process control systems
• Building automation
• Security systems
• Point-of-Sale (POS) equipment

Features

• Meets RS-485 and RS-422 standards
• ±15kV HBM ESD protection on RS-485 I/O pins
• Fractional unit load allows up to 256 devices on the bus
• Single 3.0V to 5.5V supply operation
• High data rates up to 40Mbps
• Low quiescent current (typically 220µA)
• Half-duplex transceiver
• Driver output short-circuit protection
• Thermal shutdown protection

Benefits

• Robust communication in harsh environments due to high ESD protection.
• Supports a large number of devices on the same bus, reducing system complexity and cost.
• Flexible power supply options simplify system design.
• High data rates enable fast and efficient communication.
• Low power consumption minimizes heat dissipation and improves energy efficiency.
• Reliable operation due to built-in protection features.

Additional Details

The ISL31472EIBZ-T7A is available in an 8-lead SOIC package. It is designed to operate over the industrial temperature range of -40°C to +85°C. The driver outputs are short-circuit protected, and the device includes thermal shutdown protection. Its fractional unit load allows for up to 256 transceivers on the bus without exceeding the RS-485 load limit. This makes it suitable for applications where a large number of nodes are required on the network.
