DC Electrical Characteristics
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 N package at 13.89 mW/˚C, J package 16.13 mW/˚C, M package 9.80 mW/˚C,
E package 12.20 mW/˚C, and W package 6.75 mW/˚C.
Note 4: Unless otherwise specified, min/max limits apply across the recommended operating temperature range. All typicals are given for V
Note 5: See EIA Specification RS-422 for exact test conditions.
Note 6: Measured per input. All other inputs at V
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: The DS26C31M (−55˚C to +125˚C) is tested with V
Switching Characteristics
Note 9: Skew is defined as the difference in propagation delays between complementary outputs at the 50% point.
Note 10: Output disable time is the delay from ENABLE or ENABLE being switched to the output transistors turning off. The actual disable times are less than in-
dicated due to the delay added by the RC time constant of the load.
