ISL83491IBZ-T

ISL83491IBZ-T is a BiCMOS 3.3V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. Receiver (Rx) inputs feature a “fail-safe if open” design, which ensures a logic high output if Rx inputs are floating. Driver (Tx) outputs are short-circuit protected, even for voltages exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to prevent damage if power dissipation becomes excessive. Typical applications include factory automation, security networks, building environmental control systems, industrial/process control networks, level translators (for example, RS-232 to RS-422), RS-232 “Extension Cords”.

• Operate from a single +3.3V supply (10% tolerance)
• Interoperable with 5V logic
• Single unit load allows up to 32 devices on the bus
• Current limiting and thermal shutdown for driver overload protection
• Full duplex, 10Mbps data rate
• Low current shutdown mode
• Common-mode input voltage range from -7V to +12V
• 0.65mA quiescent current
• 14 Ld SOIC package
• Temperature range from -40 to +85°C
