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 13.89 mW/˚C, and M Package 9.80 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 VCC = 5V and TA = 25˚C. Note 5: See EIA Specification RS-422 for exact test conditions. Note 6: Measured per input. All other inputs at VCC 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. www.national.com 2 |
