Beschreibung von ISO6740
The ISO674x devices are high-performance, quad-channel digital isolators ideal for cost-sensitive applications requiring up to 5000 VRMS isolation ratings per UL 1577. These devices are also certified by VDE, TUV, CSA, and CQC.
The ISO674x 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 TI’s double capacitive silicon dioxide (SiO2) insulation barrier. These devices come with enable pins which can be used to put the respective outputs in high impedance for multi-master driving applications. The ISO6740 device has all four channels in the same direction, ISO6741 device has three forward and one reverse-direction channels, and ISO6742 device has two forward and two reverse-direction channels. In the event of input power or signal loss, the default output is high for devices without suffix F and low for devices with suffix F. See Device Functional Modes section for further details.
