The ISO774x devices are high-performance, quad-channel digital isolators with 5000VRMS (DW package) and 3000VRMS (DBQ package) isolation ratings per UL 1577. This family includes devices with reinforced insulation ratings according to VDE, CSA, TUV and CQC. The ISO7741B device is designed for applications that require basic insulation ratings only.

The ISO774x 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 a 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 and to reduce power consumption. The ISO7740 device has all four channels in the same direction, the ISO7741 device has three forward and one reverse-direction channels, and the ISO7742 device has two forward and two 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.

TIDA-010085 — 使用數位隔離器的 24-VAC 多通道固態繼電器參考設計

此參考設計展示使用單一隔離的多通道固態繼電器 (SSR)。此設計採用含單一隔離式電源供應器與通用接地閘極驅動電路的多通道數位隔離器，以獨立控制多個 SSR。此設計適用 24-VAC 供電繼電器，額定電流可達 2A，但可擴充至 240VAC 和更高的額定電流。每個 SSR 通道消耗的空間小於 75 mm 2，組件的最大高度約爲 3 mm，與機電繼電器相比，可大幅節省尺寸。使用單一隔離式電源可減少機板空間及 BOM 成本。
