Average power must conform to the limit shown under the Absolute Maximum Ratings. 2 The minimum pulse width is the shortest pulse width at which the specified timing parameter is guaranteed. 3 The maximum data rate is the fastest data rate at which the specified timing parameter is guaranteed. 4 tDLH propagation delay is measured from the time of the input rising logic high threshold, VIH, to the output rising 10% level of the VOx signal. tDHL propagation delay is measured from the input falling logic low threshold, VIL, to the output falling 90% threshold of the VOx signal. See Figure 16 for waveforms of propagation delay parameters. 5 tPSK is the magnitude of the worst-case difference in tDLH and/or tDHL that is measured between ADuM7223 units at the same operating temperature, supply voltages, and output load within the recommended operating conditions. See Figure 16 for waveforms of propagation delay parameters. 6 Channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation barrier.
ELECTRICAL CHARACTERISTICS—3.3 V OPERATION
All voltages are relative to their respective ground. 3.0 V ≤ VDD1 ≤ 3.6 V, 4.5 V ≤ VDD2 ≤ 18 V, unless stated otherwise. All minimum/maximum specifications apply over TJ = −40°C to 125°C. All typical specifications are at TA = 25°C, VDD1 = 3.3 V, VDD2 = 12 V. Switching specifications are tested with CMOS signal levels.
