The ISL32741EFBZ with RS-485 Interface IC Isolated 6kV RS485, 40MB, Half-Duplex, 16.5KV ESD, 125C, 16 from Renesas is a high-speed interface buffer designed to convert logic level signals up to 40MBps into balanced low voltage differential signals. It offers 1500 Vrms signal isolation and up to 6 kV of ESD immunity, making it suitable for use in harsh industrial and medical environments. The device integrates a low pass filter on the differential input that reduces EFT and ESD susceptibility, enabling the robust protection of sensitive circuits from interference events. It also features an advanced receiver input data rate detection scheme for implementation of Half-Duplex communications. The device is integrated with RSHMICA cooling technology that supports industrial temperature range operation from -40° C to +125° C.
