The CA-IS372x devices are high-performance dual – channel digital isolators with up to 3.75kVRMS (narrow-body package) and 5kVRMS (wide-body package) isolation rating and ultra-fast data rate. The CA-IS372x devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS digital I/Os. 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-IS3720 features 2 channels transferring digital signals in one direction for applications such as isolated digital I/O. The CA-IS3721/CA-IS3722 devices have 2 channels with 1 channel in each direction, making them ideal for isolating the Tx and Rx lines of a transceiver, such as RS485, CAN etc. communication. 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-IS372x family are specified over the -40°C to +125°C operating temperature range and are available in 8-pin SOIC narrow body package, 8-pin SOIC wide body package and 16-pin SOIC wide body package.
