ISO7721FQDRQ1 Datasheet PDF - TI

●The ISO772x-Q1 devices are high-performance, dual-channel digital isolators with 5000 VRMS (DW package) and 3000 VRMS (D package) isolation ratings per UL 1577. These devices are also certified by VDE, TUV, CSA, and CQC.

●The ISO772x-Q1 devices provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. The ISO7720-Q1 device has both channels in the same direction while the -Q1 device has both channels in the opposite direction. In the event of input power or signal loss, the default output is _high_ for devices without suffix F and _low_ for devices with suffix F. See the _Device Functional Modes_ section for further details.

●Used in conjunction with isolated power supplies, these devices help prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through innovative chip design and layout techniques, the electromagnetic compatibility of the ISO772x-Q1 devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO772x-Q1 family of devices is available in 16-pin SOIC wide-body (DW) and 8-pin SOIC narrow-body (D) packages.
