Description
CA-IS373x High-Speed Triple-Channel Digital Isolators
The CA-IS373x devices are high-performance triple-channel digital isolators with precise timing characteristics and low power consumption. The CA-IS373x 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-IS3730 device has all three channels in the same direction with output enable on output side, the CAIS3731 device has two forward and one reverse-direction channels with output enable on both sides, and the CA-IS3735 device has the same channel configuration as CA-IS3730 without output enable. 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-IS373x 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-IS373x devices are available in 16-pin narrow body SOIC and 16-pin wide body SOIC packages. All products have > 2.5kVrms isolation rating, and products in wide-body packages support insulation with standing up to 5kVrms.
