CA-IS3721LW-Q1
Active
Automotive, Dual Channel Standard Digital Isolators
The CA-IS3710 devices are high-performance singlechannel, unidirectional digital isolator with up to 3.75kVRMS isolation rating and ultra-fast data rate. This device offers 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. Internal isolation channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier, the integrated Schmitt trigger on the input provides excellent noise immunity.
The CA-IS3710 devices feature default outputs. 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-IS3710 series devices are specified over the -40°C to +125°C operating temperature range and are available in 8-pin SOIC narrow body package.
