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 TJ = 25°C, VDD1 = 3.3 V, VDD2 = 12 V. Switching
specifications are tested with CMOS signal levels.

1 Short-circuit duration less than 1 µs. 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 20 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 units at the same operating temperature, supply voltages, and output
load within the recommended operating conditions. See Figure 20 for waveforms of propagation delay parameters.
6 Channel-to-channel matching is the absolute value of the difference in propagation delays between the two channels.
