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