The SI8461AA-B-IS1 is a digital isolator manufactured by Silicon Labs that is a high performance, six-channel, single-bit, digital isolator with a 1kilovolt-rated isolation barrier. It features five forward channels (driving a load) and one reverse channel (receiving the input) with a maximum data rate of up to 43 MHz. The device has minimal power and space requirements, making it suitable for a wide range of applications. The SI8461AA-B-IS1 is designed with enhanced common-mode transient immunity and provides galvanic isolation and enhanced safety against voltage transients, surges, and AC noise. The device is also resistant to interference caused by ambient light, humidity, and extreme temperatures. This digital isolator comes with fault protection and built-in ESD protection, providing robust operation under harsh operating conditions.
