Combining high speed, complementary metal-oxide V V 4 ENCO DE DECO DE 13 IC OC semiconductor (CMOS) and monolithic air core transformer V V 5 DECO DE ENCO DE 12 OD ID technology, these isolation components provide outstanding V V 6 DECO DE ENCO DE 11 OE IE performance characteristics superior to alternatives such as NI C NI C 7 10 optocoupler devices and other integrated couplers. The maximum GND 8 9 GND 1 2 propagation delay is 13 ns with a pulse width distortion of less Figure 3. ADuM252N Functional Block Diagram than 4.5 ns at 5 V operation. Channel to channel matching of propagation delay is tight at 4.0 ns maximum. The ADuM250N/ADuM251N/ADuM252N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.0 kV rms (see the Ordering Unlike other optocoupler alternatives, dc correctness is ensured Guide). The devices operate with the supply voltage on either in the absence of input logic transitions. Two different fail-safe side ranging from 1.7 V to 5.5 V, providing compatibility with options are available by which the outputs transition to a predeter- lower voltage systems as well as enabling voltage translation mined state when the input power supply is not applied. functionality across the isolation barrier. 1 Protected by U.S. Patents 5,952,849 6,873,065 6,903,578 and 7,075,329.
