Note 1:
Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The table of “Electrical Characteristics” provide conditions for actual device operation.
Note 2:
Unless otherwise specified, all voltages are referenced to ground. All currents into device pins are positive; all currents out of device pins are negative.
Note 3:
Ratings apply to ambient temperature at 25°C. Above this temperature derate SSOP (MEA) Package 10.9 mW/°C.
Note 4:
Unless otherwise specified, min/max limits apply across the −40°C to 85°C temperature range. All typicals are given for V
CC
= 5V and T
A
= 25°C.
Note 5:
See TIA/EIA-422-B for exact test conditions.
Note 6:
Measured per input. All other inputs at V

or GND.

Note 7:
This is the current sourced when a high output is shorted to ground. Only one output at a time should be shorted.
Note 8:
Skew is defined as the difference in propagation delays between complementary outputs at the crossing point.
Note 9:
Output disable time is the delay from the control input being switched to the output transistors turning off. The actual disable times are less than indicated
due to the delay added by the RC time constant of the load.
