I2c digital isolator11/26/2023 ![]() ![]() 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. ![]() 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. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO 2) insulation barrier. The ISO774x-Q1 device s provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. This family of devices has reinforced insulation ratings according to VDE, CSA, TUV and CQC. 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. ![]() Extra-wide SOIC (DWW-16), wide-SOIC (DW-16) and QSOP (DBQ-16) package options.☘ kV IEC 6 contact discharge protection across isolation barrier.System-level ESD, EFT, and surge immunity.Robust electromagnetic compatibility (EMC).Low propagation delay: 10.7 ns typical (5-V Supplies).Low power consumption, typical 1.5 mA per channel at 1 Mbps.Default output high ( ISO774 x) and low ( ISO774 xF) options.>100-year projected lifetime at 1500 V RMS working voltage.Documentation available to aid functional safety system design: ISO7740-Q1, ISO7741-Q1, ISO7742-Q1.Device temperature Grade 1: –40☌ to 125☌ ambient operating temperature.AEC-Q100 qualified with the following results:.If you do not allow these cookies, you will experience reduced relevant content.
