AC Specifications
All voltages are relative to their respective ground. All minimum/maximum specifications apply over the entire recommended operating
range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = 5 V, and VDD2 = 5 V, unless otherwise noted. See Figure 3
for a timing test diagram.

tPLH12 propagation delay is measured from the Side 1 input logic threshold to an output value of 0.7 VDD2.
2
tPHL12 propagation delay is measured from the Side 1 input logic threshold to an output value of 0.4 V.
3
tPLH21 propagation delay is measured from the Side 2 input logic threshold to an output value of 0.7 VDD1.
4
tPHL21 propagation delay is measured from the Side 2 input logic threshold to an output value of 0.9 V.
5
CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate
that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient
magnitude is the range over which the common mode is slewed.
