The digital signal is modulated with RF carrier generated by the internal oscillator at the Transmitter side. Then it is transferred through the capacitive isolation barrier and demodulated at the Receiver side. The NSi814x devices are high reliability quad-channel digital isolator with AEC-Q100 qualified. The NSi814x device is safety certified by UL1577 support several insulation withstand voltages (3.75kVrms, 5kVrms), while providing high electromagnetic immunity and low emissions at low power consumption. The data rate of the NSi814x is up to 150Mbps, and the common-mode transient immunity (CMTI) is up to 150kV/us. The NSi814x device provides digital channel direction configuration and the default output level configuration when the input power is lost. Wide supply voltage of the NSi814x device support to connect with most digital interface directly, easy to do the level shift. High system level EMC performance enhance reliability and stability of use. The NSi814x has a default output status when VDDIN is unready and VDDOUT is ready as shown in Table 4.1, which helps for diagnosis when power is missing at the transmitter side. The output B follows the same status with the input A within 60us after powering up.

The capacitor should be placed as close as possible to the package. Figure 5.1 show the recommended schematic diagram , Figure 5.2 to Figure 5.3 show the recommended PCB layout, make sure the space under the chip should keep free from planes, traces, pads and via. To enhance the robustness of a design, the user may also include resistors (50–300 Ω ) in series with the inputs and outputs if the system is excessively noisy. The series resistors also improve the system reliability such as latch-up immunity. The typical output impedance of an isolator driver channel is approximately 50 Ω, ±40%. When driving loads where transmission line effects will be a factor, output pins should be appropriately terminated with controlled impedance PCB traces.
