ISO7720 - Texas Instruments

ISO7720 Reinforced and Basic Dual-Channel Digital Isolators

The ISO772x devices are high-performance, dualchannel digital isolators with 5000 VRMS (DW and DWV packages) and 3000 VRMS (D package) isolation ratings per UL 1577. This family includes devices with reinforced insulation ratings according to VDE, CSA, TUV and CQC.The ISO7721B device is designed for applications that require basic insulation ratings only. Th.
