TI ISO7720FDR

Емкостная связь23000 Вrms

Overview

The ISO772x devicesare high-performance, dual-channel digital isolators with 5000 VRMS (DW and DWV packages) and 3000VRMS (D package) isolation ratings per UL 1577. These devices are alsocertified by VDE, TUV, CSA, and CQC.

Used in conjunction with isolated power supplies, these devices help prevent noisecurrents on data buses, such as RS-485, RS-232, and CAN, from damaging sensitive circuitry. Through innovative chip designand layout techniques, the electromagnetic compatibility of the ISO772x devices has beensignificantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. TheISO772x family of devices isavailable in 16-pin SOIC wide-body (DW), 8-pin SOIC wide-body (DWV),and 8-pin SOIC narrow-body (D) packages.
