Reinforced Quad Channel Digital Isolators

The CA-IS384x devices are high-performance quad-channel digital isolators with precise timing characteristics and low power consumption. The CA-IS384x 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-IS3840 device has all four channels in the same direction with output enable on the output side (B side), the CA-IS3841 device has three forward and one reverse-direction channels with output enable on both sides, the CA-IS3842 device has two forward and two reverse-direction channels with output enable on both sides. 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-IS384x 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-IS384x devices are available in 16-pin wide body SOIC packages. Products support insulation withstanding up to 5.7kVrms (wide body) and 7.5kVrms (extra wide body)
