Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion (PWD) of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum. The ADuM220N/ADuM221N/ADuM225N/ADuM226N 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 Guide). The devices operate with the supply voltage on either side ranging from 1.8 V to 5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. Two different fail-safe options are available, in which FUNCTIONAL BLOCK DIAGRAMS GND1 1 NIC 2 VDD1 3 VIA 4 VIB 5 NIC 6 GND1 7 NIC 8 ENCODE ENCODE ADuM220N DECODE DECODE Figure 1. 16 GND2 15 NIC 14 VDD2 13 VOA 12 VOB 11 NIC 10 NIC 9 GND2 14116-001 GND1 1 NIC 2 VDD1 3 VOA 4 VIB 5 NIC 6 GND1 7 NIC 8 DECODE ENCODE ADuM221N ENCODE DECODE Figure 2. 16 GND2 15 NIC 14 VDD2 13 VIA 12 VOB 11 NIC 10 NIC 9 GND2 14116-002 VDD1 1 VIA 2 VIB 3 GND1 4 ENCODE ENCODE ADuM225N DECODE DECODE Figure 3. 8 VDD2 7 VOA 6 VOB 5 GND2 14116-003 VDD1 1 ADuM226N 8 VDD2 VOA 2 DECODE ENCODE 7 VIA VIB 3 ENCODE DECODE 6 VOB 14116-004 GND1 4 5 GND2 Figure 4. the outputs transition to a predetermined state when the input power supply is not applied or the inputs are disabled.
