The ISO7721FQDRQ1 device is a high-performance dual-channel digital isolator that provides 5000VRMS (DW package) and 3000VRMS (D package) isolation ratings according to UL 1577. These devices are also VDE, TUV, CSA and CQC certified.

While isolating complementary metal oxide semiconductor (CMOS) or low voltage complementary metal oxide semiconductor (LVCMOS) digital I/Os, the ISO7721FQDRQ1 device provides high electromagnetic immunity and low emissions, while offering low power consumption. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulating barrier. The ISO7720-Q1 device has two in-direction channels, while the -Q1 device has two reverse-direction channels. If there is a loss of input power or signal, devices without the suffix F will output a high level by default, and devices with the suffix F will output a low level by default. See the Device Functional Modes section for more details.

When the ISO7721FQDRQ1 is used with isolated power supplies, these devices help prevent noise currents on the data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuits. With innovative chip design and routing techniques, the ISO7721FQDRQ1 device has significantly enhanced electromagnetic compatibility to mitigate system-level ESD, EFT and surge issues and comply with emissions standards. The ISO7721FQDRQ1 family of devices is available in 16-pin SOIC wide body (DW) and 8-pin SOIC narrow body (D) packages.
