The UMISO7742 series are high-performance four-channel, unidirectional digital isolators with 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 UMISO7742 series provide further design flexibility with two channels in each direction. The UMISO7742 series come with individual enable control pins for each side of the isolator which can be used to put the outputs in high impedance for multi-master driving applications to reduce power consumption.

The UMISO7742 series 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 table for suffixes associated with each option.

The UMISO7742 series are available in WSOP16 wide body package. The devices are characterized over ambient free-air temperatures from –40°C to 125°C.
