1
The supply current values are for both channels combined when running at identical data rates. Output supply current values are specified with no output load present.
2
The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.
3
The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.

PHL
propagation delay is measured from the 50% level of the falling edge of the V
Ix
signal to the 50% level of the falling edge of the V
Ox
signal. t
PLH
propagation delay is
measured from the 50% level of the rising edge of the V
Ix
signal to the 50% level of the rising edge of the V
Ox
signal.

t
PSK
is the magnitude of the worst-case difference in t
PHL
and/or t
PLH
that is measured between units at the same operating temperature, supply voltages, and output
load within the recommended operating conditions.

Codirectional 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. Opposing directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with
inputs on opposing sides of the isolation barrier.

is the maximum common-mode voltage slew rate that can be sustained while maintaining V
Ox

DD2
. CM
L
is the maximum common-mode voltage slew rate
that can be sustained while maintaining V
Ox
< 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.
8
Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in the signal data rate.
