Beschreibung von ISO6740-Q1
The ISO674x-Q1 devices are high-performance, quad-channel digital isolators designed for cost-sensitive applications requiring up to 5000VRMS isolation ratings per UL 1577. These devices are also certified by VDE, TUV, CSA, and CQC.
The ISO674x-Q1 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-controller driving applications. The ISO6740-Q1 device has all four channels in the same direction, the ISO6741-Q1 device has three forward and one reverse-direction channels, and the ISO6742-Q1 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 also Device Functional Modes section.
Used in conjunction with isolated power supplies, the ISO674x-Q1 devices help prevent noise currents on data buses, such as CAN and LIN from damaging sensitive circuitry. Through remarkable chip design and layout techniques, the electromagnetic compatibility of the ISO674x-Q1 devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO674x-Q1 family of devices is available in a 16-pin SOIC wide-body (DW) package and is a pin-to-pin upgrade to the older generations.
