ELECTRICAL CHARACTERISTICS (V
Note 1: Unless otherwise specified, min/max limitsapply across the recommended operating temperatur e range. All typicals are given for V
T
Note 2: See EIASpecification RS422 for exact test conditions.
Note 3: Measured per pin input. Allother input at V
Note 4: This is the current sourced when a high output is shorted to ground. Only one output at time should be shorted.
SWITCHING CHARACTERISTICS (V
Note 1: Unless otherwise specified. min/max limitsapply across the recommended operating temperatur e range. All typical are given for V
T
Note 2: Skewis defined as the difference in propagation delays between complementary outputs at the 50% point.
Note 3: Outputdisable time is the delay from the control input being switched to the output transistorsturning off. The actual disable times are less than
indicated due to the delay added by RC time constant ofthe load.
