Chipanalog CA-IS3760CHW Digital Isolator

Chipanalog CA-IS3760CHW

The CA-IS376xC devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS digital I/O. Each isolation channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier, and each channel input integrated Schmitt trigger to provide excellent noise immunity. The CA-IS3760C features 6 channels transferring digital signals in one direction and output enable for the B side is active-high. The CA-IS3761C device has three forward and one reverse-direction channels, making it ideal for applications such as isolated SPI, RS-485 communication. The CA-IS3762C provides further design flexibility with two channels in each direction. The CA-IS3763 provides further design flexibility with three channels in each direction. When the input is either not powered or is open-circuit, the default output is low for devices with suffix L and high for devices with suffix H. The CA-IS376xC family are specified over the -40°C to +125°C operating temperature range and are available in 16-pin SOIC wide body package and 16-pin SOIC wide body package.
