Description

The API772X are high-performance dual-channel digital isolators with 5000VRMS (SO-8W (Type CJ) package) per UL 1577. This family insulation level can fulfill reinforce and basic isolation requirements, according to VDE, UL, CQC, etc. The data rate of API772X is up to 100Mbps. It provides digital channel direction configuration and the default output level. It can also operate under wide supply voltage of 2.5V to 5.5V.

The API772X provide strong electromagnetic immunity and low emissions at low-power consumption. This family has a minimum of 150kV/µs common-mode transient immunity (CMTI). The API7720 device has both channels in the same direction while the API7721/22 device have both channels in the opposite direction. The default output is high for devices without suffix F and low for devices with suffix F. See Device Functional Modes section for further details.
