Product Description
Product Overview
The NSi8100NC devices are low-cost, bidirectional isolators compatible with the I2C interface. Safety certified by UL1577, they support insulation withstand voltages of 3.75kVrms and 5kVrms, offering high electromagnetic immunity and low emissions with low power consumption. The NSi8100NC supports I2C clock rates up to 2MHz and boasts a common-mode transient immunity (CMTI) of up to 150kV/us. Its wide supply voltage range allows direct connection to most digital interfaces, facilitating level shifting. These isolators enhance system reliability and stability through high system-level EMC performance.
