Combining high speed, complementary Figure 3. metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide ADuM226N 1 8 V V outstanding performance characteristics superior to alternatives DD1 DD2 such as optocoupler devices and other integrated couplers. The 2 DECODE ENCODE 7 V V OA IA maximum propagation delay is 13 ns with a pulse width distortion 3 ENCODE DECODE 6 V V IB OB (PWD) of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum. 4 5 GND GND 1 2 The ADuM220N/ADuM221N/ADuM225N/ADuM226N data Figure 4 channels are independent and are available in a variety of the outputs transition to a predetermined state when the input configurations with a withstand voltage rating of 5.0 kV rms (see power supply is not applied or the inputs are disabled.The the Ordering Guide).
