Description
CA-IS3722HS Dual Channel Standard Digital Isolators
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/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‐IS3720 features two 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.
