ISL83483IBZ-T

The ISL83483IBZ-T is a BiCMOS powered Single Transceiver meets both the RS-485 and RS-422 standards for balanced communication. Unlike competitive devices, this 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
• Low current shutdown mode
