The SI8431AB-C-IS1 is a digital isolator manufactured by Silicon Labs. It is a 2.5 kV isolator with 2 forward and 1 reverse 3-channel Isolation. It includes three digital channels that allow communication between two circuits that have different voltage levels and ground references. It is built on Silicon Labs’ patented energy-saving isolation technology, which gives the device low power consumption, high speed, and reliable operations, even in the presence of high transients. The SI8431AB-C-IS1 has a normal operating temperature of 0°C to +70°C, and a wide supply voltage range of 4.5 V to 5.5 V. This isolator is certified to meet the international safety standard requirements, making it suitable for use in medical, industrial, and other applications.
