SI8642ED-B-ISR +BOM

High-speed communication

SI8642ED-B-ISR General Description

Silicon Labs' SI8642ED-B-ISR is a dual-channel digital isolator that offers reliable isolation between two circuits in high-speed communication applications. With a maximum data rate of 150 Mbps, reinforced insulation, and a wide operating voltage range, this isolator provides increased safety and protection. Its high CMTI performance makes it suitable for noisy industrial environments, while its low power consumption and compact SOIC-16 package make it perfect for space-constrained applications. Furthermore, its RoHS compliance and wide temperature range make it versatile for various industrial and automotive applications
