The UMISO7720 series are high-performance dual-channel, unidirectional digital isolators with 3.75kVRMS (narrow body package) and 5kVRMS (wide-body package) isolation rating and DC to 150Mbps ultra-fast data rate. The 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 in automotive applications.

The UMISO7720 series feature two channels transferring signals in one direction. The UMISO7720 series features 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 table for suffixes associated with each option.

The UMISO7720 series are available in SOP8 narrow body package, WSOP8 wide body package and WSOP16 wide body package. The devices are characterized over ambient free-air temperatures from –40°C to 125°C.
