The ISO7741E-Q1automotive device is a grade 0, high-performance, quad-channel digital isolator with 5000 VRMS isolation ratings per UL 1577. This device has reinforced insulation ratings according to VDE, CSA, TUV and CQC. The high temperature range up to 150°C makes this device suitable for applications like belt starter generators, water pumps, cooling fans, soot sensors etc.,which may experience greater than 125°C ambient temperature.

The ISO7741E-Q1 device 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 (SiO2) insulation barrier. This device comes 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 ISO7741E-Q1 device has three forward and one 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.
