ISO7741DBQ  Description

The ISO774x devices are high-performance, quad-channel digital isolators with 5000 VRMS (DW package) and 3000 VRMS (DBQ package) isolation

ratings per UL 1577. This family includes devices with reinforced insulation ratings according to VDE, CSA, TUV, and CQC. The ISO7741B device is designed for

applications that require basic insulation ratings only.
