ISL32433EIUZ-T

Overview

The ISL32433EIUZ-T is a single RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V, supporting standard 3.3 V and 5 V logic levels. The device achieves data transmission rates up to 1 Mb/s with differential output signaling. It functions reliably across an extended industrial temperature range from -40 °C to +85 °C. The component is housed in an MSOP-10 surface-mount package and includes one driver and one receiver channel.
