Digital Isolator ICs adopt isolating CMOS to provide high electromagnetic immunity and low emissions at low-power consumption. Isolator data channels are independent and different models have different transmission directions with a withstand voltage rating of 3kVrms and the data rate from DC up to10Mbps. Digital isolators with power supply voltage on either side ranging from 3.0V to 5.5V enable working, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. We hope these digital signal isolator ICs are an ideal fit for your application needs and can simplify your design with specific digital isolator ICs.
TDA51S-41HC is a family of high-performance reinforced digital isolators with an integrated isolated DC-DC converter. TDA51S-41HC eliminate the need for a separate, isolated power supply, which results in a small form factor, total isolation solution. TDA51S-41HC device has three forward and one reverse-direction channels, and it has fail-safe mode option. If the input signal is lost, default output is low for devices with H. In addition, other channel communication types, such as two forward channels and two reverse channels, four forward channels, four reverse channels,and many other channel combination types are under development.
