The q denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.
VDD = 5V ±5% (Notes 2, 3) VID = 1.5V, VCM = 2.5V, unless otherwise noted.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All currents into the device pins are positive; all currents out of the
device pins are negative.
Note 3: All typicals are given for VDD = 5V, TA = 25°C.
Note 4: Guaranteed by design, but not tested.
Note 5: Worst-case
tPLH – tPHLskew for a single receiver in a package
over the full operating temperature range.
Note 6: Maximum difference between any two tPLH or tPHL transitions in a
single package over the full operating temperature range.
Note 7: Short-circuit current does not represent output drive capability.
When the output detects a short-circuit condition, output drive current is
significantly reduced until the short is removed.
The q denotes specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VDD = 5V ±5% (Notes 2, 3) per receiver, unless otherwise noted.
