TI ISO7221ADR

容性耦合22500Vrms

Overview

The ISO7220x and ISO7221x family devices are dual-channel digital isolators. Tofacilitate PCB layout, the channels are oriented in the same direction in the ISO7220x and inopposite directions in the ISO7221x. These devices have a logic input and output buffer separatedby TI’s silicon-dioxide (SiO2) isolation barrier, providing galvanicisolation of up to4000VPK per VDE. Used in conjunction with isolated power supplies, these devicesblock high voltage and isolate grounds, as well as prevent noise currents on a data bus or othercircuits from entering the local ground and interfering with or damaging sensitivecircuitry.
