TERMINOLOGY
I
DD1(Q)
I
DD1(Q)
is the minimum operating current drawn at the V
DD1
pin when there is no external load at V
ISO
and the I/O pins
are operating below 2 Mbps, requiring no additional dynamic
supply current.
I
DD1(MAX)
I
DD1(MAX)
is the input current under full dynamic and V
ISO
load
conditions.
t
PHL
Propagation Delay
t
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
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.
Propagation Delay Skew (t
PSK
)
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.
Channel-to-Channel Matching
Channel-to-channel matching is the absolute value of the
difference in propagation delays between two channels when
operated with identical loads.
Minimum Pulse Width
The minimum pulse width is the shortest pulse width at which
the specified pulse width distortion is guaranteed.
Maximum Data Rate
The maximum data rate is the fastest data rate at which the
specified pulse width distortion is guaranteed.
