SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V OPERATION
All typical specifications are at TA = 25°C, VDD1 = VDD2 = 5 V. Minimum/maximum specifications apply over the entire recommended operation
range of 4.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 V, and −40°C ≤ TA ≤ +105°C, unless otherwise noted. Switching specifications are tested
with CL = 15 pF and CMOS signal levels, unless otherwise noted.

1 tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.
2 Codirectional 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.
3 Opposing directional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposite sides of the
isolation barrier.
