Texas Instruments ISO774x/ISO774x-Q1 Quad-Channel Digital Isolators are high-performance, quad-channel digital isolators with 5000VRMS (DW package) and 2500VRMS (DBQ package) isolation ratings per UL 1577. These devices have reinforced insulation ratings according to VDE, CSA, TUV and CQC standards. These 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. These 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/ISO7740-Q1 devices have all four channels in the same direction, the ISO7741/ISO7741-Q1 devices have three forward and one reverse-direction channels and the ISO7742/ISO7742-Q1 devices have two forward and two reverse-direction channels. The ISO774x/ISO774x-Q1 devices are AEC-Q100 qualified for automotive applications.
