CA-IS3730LW High‐Speed Triple‐Channel Digital Isolators

CA-IS3730LW 

The CA‐IS373x devices are high‐performance triple‐ channel digital isolators with up to 3.75kVRMS (narrow‐body package) or 5kVRMS (wide‐body package) isolation rating and DC to150Mbps ultra‐fast data rate. The CA‐IS373x devices offer high electromagnetic immunity and low emissions at low power consumption while isolating different ground domains and block high‐voltage/high‐current transients from sensitive or human interface circuitry. Each isolation channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier, the integrated Schmitt trigger on each input provide excellent noise immunity. 

The CA‐IS3730 features 3 channels transferring digital signals in one direction for applications such as isolated digital I/Os. 

The CA‐IS3731 device has 2 forward and 1 reverse‐direction channels. All of the devices in this family come with enable pins which can be used to put the outputs in high impedance for multi‐master driving applications to reduce power consumption. 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, see the Ordering Information for suffixes associated with each option.

The CA‐IS373x family devices are specified over the ‐40°C to +125°C operating temperature range. Both CA‐IS3730 and CA‐IS3731 are available in 16‐pin SOIC narrow body package and 16‐pin SOIC wide body package. Also, the CA‐IS3731 provides 16‐pin SSOP narrow body package.
