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 (VCC) −0.5 to 7.0V DC Voltage (VIN) −1.5 to VCC +1.5V DC Output Voltage (VOUT) −0.5 to 7V Clamp Diode Current (IIK, IOK) ±20 mA DC Output Current, per pin (IOUT) ±150 mA DC VCC or GND Current (ICC) ±500 mA Storage Temperature Range (TSTG) −65°C to +150°C Junction Temperature +150°C Maximum Power Dissipation (PD) @ 25°C (Note 3) Thermal Resistance θJA 81.7°C/W θJC 31.7°C/W Lead Temperature (TL) (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 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 VCC = 5V and TA = 25°C. Note 5: See TIA/EIA-422-B for exact test conditions. Note 6: Measured per input. All other inputs at VCC or GND. www.national.com 2 DS89C387

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. Note 10: CPD determines the no load dynamic power consumption, PD = CPD V2CC f + ICC VCC, and the no load dynamic current consumption, IS = CPD VCC f + ICC. Note 11: ESD Rating: HBM (1.5 kΩ, 100 pF) Inputs ≥ 1500V Outputs ≥ 1000V EIAJ (0 Ω, 200 pF) All Pins ≥ 350V 3 www.national.com DS89C387
