Texas Instruments ISO773x/-Q1三通道數位隔離器
Texas Instruments ISO773x/ISO773x-Q1三通道數位隔離器具有每UL 1577 5000VRMS（DW封裝）和2500VRMS（DBQ封裝）額定隔離值。 這些裝置可以低功耗提供高電磁抗擾性和低輻射性，同時隔離CMOS或LVCMOS數位I/O。 每個通道均擁有以矽二極管(SiO2)絕緣擋板分開的邏輯輸入和輸出緩衝器。 該裝置附帶啟動引腳，可使各自的輸出達到適合多主體驅動應用的高阻抗狀態，還可以降低功耗。 ISO7730/ISO7730-Q1裝置的三個通道均在同一方向，ISO7730/ISO7730-Q1裝置擁有兩個前向和一個反向通道。 如果輸入功率或訊號丟失，不帶F後綴的裝置擁有高預設輸出， 帶F後綴的裝置擁有低預設輸出。ISO773x-Q1裝置已經過ISO773x-Q1認證適合汽車應用。
