ISO7762QDBQRQ1 General Description

The ISO776x-Q1 devices are high-performance, six-channel digital isolators with 5000-V_RMS (DW package) and 3000-V_RMS (DBQ package) isolation ratings per UL 1577. This family of devices is also certified according to VDE, CSA, TUV and CQC.

The ISO776x-Q1 family of devices provides 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 logic-output buffer separated by a double capacitive silicon dioxide (SiO₂) insulation barrier. The ISO776x-Q1 family of devices is available in all possible pin configurations such that all six channels are in the same direction, or one, two, or three channels are in reverse direction while the remaining channels are in forward direction. If the input power or signal is lost, 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, this family of devices helps prevent noise currents on data buses, such as CAN and LIN, or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO776x-Q1 family of devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO776x-Q1 family of devices is available in 16-pin SOIC and SSOP packages.
