CA-IS3820LW
Active
Reinforced Dual Channel Digital Isolators
The CA-IS382X devices are high-performance dual - channel digital isolators with precise timing characteristics and low power consumption. The CA-IS382X devices provide high electromagnetic immunity and low emissions, while isolating CMOS digital I/Os. All device versions have Schmitt trigger input for high noise immunity. Each isolation channel consists of a transmitter and a receiver separated by silicon dioxide (SiO2) insulation barrier. The CA-IS382X device has one forward and one reverse-direction channels. All devices have fail-safe mode option. If the input power or signal is lost, default output is low for devices with suffix L and high for devices with suffix H.
CA-IS382X devices has high insulation capability to handle noise and surge on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. High CMTI ability promises the correct transmission of digital signal. The CA-IS382x devices are available in SOIC8/SOIC16 wide body package and SOIC16 extra wide body package. Products support insulation withstanding up to 5.7kVrms (wide body) and 7.5kVrms (extra wide body)
