Renesas Electronics Corporation Integrated Circuits (ICs) - Interface - Drivers, Receivers, Transceivers ISL83088EIUZ-T

The ISL83088EIUZ-T is a half-duplex RS-485/RS-422 transceiver designed for balanced communication. It operates on a single 5V power supply with a tolerance of 10% (4.5V to 5.5V) and features ±15kV ESD protection on all pins, ensuring robust performance in electrically noisy environments. The device supports data rates up to 10 Mbps and presents a low bus current of +125µA/-75µA, allowing for a true 1/8 unit load, which enables connection of up to 256 devices on the bus without the need for repeaters. The transceiver includes a full fail-safe design for receiver inputs, ensuring a logic high output when inputs are floating, shorted, or terminated but undriven. It also features hot plug circuitry, allowing the Tx and Rx outputs to remain in a high impedance state during power-up and power-down sequences. The ISL83088EIUZ-T is packaged in an 8-lead MSOP, making it suitable for applications where board space is a concern. This product is ideal for use in automated utility meter reading systems, factory automation, and other high node count systems.
