... ISL32490E, ISL32492E, ISL32493E, ISL32495E, ISL32496E, ISL32498E increases system reliability. The CMR increases to ±25V, while the RS-485 bus pins (receiver inputs and driver outputs) include fault protection against voltages and transients up to ±60V. Additionally, larger-than-required differential output voltages (V ) increase noise immunity, while the ±16.5kV built-in ESD OD protection complements the fault protection ...
