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 (Q)
reflects the minimum current operating
condition.
I
DD1 (D)
I
DD1 (D)
is the typical input supply current with all channels
simultaneously driven at a maximum data rate of 25 Mbps with
full capacitive load representing the maximum dynamic load
conditions. Resistive loads on the outputs should be treated
separately from the dynamic load.
I
DD1 (MAX)
I
DD1 (MAX)
is the input current under full dynamic and V
ISO
load
conditions.
I
SO (LOAD)
I
SO (LOAD)
is the current available to the load.
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, t
PSKCD
/t
PSKOD
Channel-to-channel matching is the absolute value of the
difference in propagation delays between the 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.
