Product Description

The ISL83491IBZ is a BiCMOS powered Single Transceiver meets both the RS-485 and RS-422 standards for balanced communication. Unlike competitive devices, this Intersil family is specified for 10% tolerance supplies. It utilizes slew rate limited drivers which reduce EMI and minimizes reflections from improperly terminated transmission lines or un-terminated stubs in multi-drop and multipoint applications. Logic inputs accept signals in excess of 5.5V, making them compatible with 5V logic families. Receiver (Rx) inputs feature a fail-safe if open design, which ensures a logic high output if Rx inputs are floating. The device presents a single unit load to the RS-485 bus, which allows up to 32 transceivers on the network. 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.
Interoperable with 5V logic
Single unit load allows up to 32 devices on the bus
Slew rate limited versions for error free data transmission
Full duplex and half duplex pin-outs
Current limiting and thermal shutdown for driver overload protection
