Combining barrier. high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation Unlike other optocoupler alternatives, dc correctness is ensured in components provide outstanding performance characteristics the absence of input logic transitions. Two different fail-safe options superior to alternatives such as optocoupler devices and other are available in which the outputs transition to a predetermined integrated couplers. The maximum propagation delay is 13 ns state when the input power supply is not applied or the inputs with a pulse width distortion of less than 3 ns at 5 V operation. are disabled. Channel matching is tight at 3.0 ns maximum. The ADuM120N0 is pin-compatible with the ADuM1285, and The ADuM120N/ADuM121N data channels are independent and the ADuM120N1 is pin-compatible with the ADuM1280 and are available in a variety of configurations with a withstand voltage the ADuM1200. The ADuM121N0 is pin-compatible with rating of 3 kV rms (see the Ordering Guide). The devices operate ADuM1286, and the ADuM121N1 is pin-compatible with the with the supply voltage on either side ranging from 1.8 V to 5 V, ADuM1281 and the ADuM1201. 1 Protected by U.S. Patents 5,952,849 6,873,065 6,903,578 and 7,075,329.
