2 / 8 page  Absolute Maximum Ratings (Notes 1, 2) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications. Supply Voltage (V CC) −0.5 to 7.0V DC Voltage (V IN) −1.5 to V CC +1.5V DC Output Voltage (V OUT ) −0.5 to 7V Clamp Diode Current (I IK ,IOK) ±20 mA DC Output Current, per pin (I OUT ) ±150 mA DC V CC or GND Current (ICC) ±150 mA Storage Temperature Range (T STG ) −65˚C to +150˚C Maximum Power Dissipation (P D) @ 25˚C (Note 3) Plastic “N” Package 1736 mW SOIC Package 1226 mW Lead Temperature (T L) (Soldering 4 sec) 260˚C This device does not meet 2000V ESD rating.

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 |
