SI8640EC-B-IS1 General Description

Silicon Labs' SI8640EC-B-IS1 digital isolator is a robust and high-performance solution for signal isolation in a variety of industrial and power-related applications. With four independent bidirectional channels and a maximum data rate of 150 Mbps, it delivers reliable and fast signal transmission. The device's wide operating voltage range of 2.5 to 5.5V ensures compatibility with different power systems, making it suitable for diverse application requirements. Its reinforced insulation with a working voltage of 5600 Vrms provides a high level of safety and reliability, especially in high-isolation applications. Furthermore, the SI8640EC-B-IS1's low power consumption of only 2.5 mA per channel contributes to energy efficiency in designs with strict power constraints. Its compact form factor and small SOIC-16 package make it easy to integrate into space-constrained designs
