TERMINOLOGY
IDD1(Q)
tPLH Propagation Delay
IDD1(Q) is the minimum operating current drawn at the VDD1 pin
when there is no external load at VISO and the I/O pins are oper-
ating below 2 Mbps, requiring no additional dynamic supply
current. IDDIO(Q) reflects the minimum current operating
condition.
tPLH propagation delay is measured from the 50% level of the
rising edge of the VIx signal to the 50% level of the rising edge of
the VOx signal.
Propagation Delay Skew (tPSK
)
tPSK is the magnitude of the worst-case difference in tPHL and/or
IDD1(D)
tPLH that is measured between units at the same operating
temperature, supply voltages, and output load within the
recommended operating conditions.
IDD1(D) is the typical input supply current with all channels
simultaneously driven at 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.
Channel-to-Channel Matching
Channel-to-channel matching is the absolute value of the
difference in propagation delays between the two channels
when operated with identical loads.
IDD1(MAX)
IDD1(MAX) is the input current under full dynamic and VISO load
conditions.
Minimum Pulse Width
The minimum pulse width is the shortest pulse width at which
the specified pulse width distortion is guaranteed.
tPHL Propagation Delay
tPHL propagation delay is measured from the 50% level of the
falling edge of the VIx signal to the 50% level of the falling edge
of the VOx signal.
Maximum Data Rate
The maximum data rate is the fastest data rate at which the
specified pulse width distortion is guaranteed.
