The ISO774x-Q1 automotive device s are high-performance, quad-channel digital isolator s with 5700 V RMS (DWW package), 5000 V RMS (DW package) and 3000 V RMS (DBQ package) isolation ratings per UL 1577. This family of devices has reinforced insulation ratings according to VDE, CSA, TUV and CQC.

The ISO774x-Q1 device s 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 double capacitive silicon dioxide (SiO 2) insulation barrier. These device s come with enable pins which can be used to put the respective outputs in high impedance for multi-master driving applications and to reduce power consumption. The ISO7740-Q1 device has all four channels in the same direction, the ISO7741-Q1 device has three forward and one reverse-direction channels , and the ISO7742-Q1 device has two forward and two reverse-direction channels. If the input power or signal is lost, 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 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 ISO774x-Q1 device s have been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO774x-Q1 device s are available in 16-pin wide SOIC (DW) and QSOP (DBQ) package s. ISO7741-Q1 is also available in extra-wide SOIC (DWW) package.
