3 / 10 page Absolute Maximum Ratings (Note 2) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications. Supply Voltage (V CC) −0.5V to +7.0V DC Input Diode Current (I IK) V I = −0.5V −20 mA V I = VCC + 0.5V +20 mA DC Input Voltage (V I) −0.5V to V CC + 0.5V DC Output Diode Current (I OK) V O = −0.5V −20 mA V O = VCC + 0.5V +20 mA DC Output Voltage (V O) −0.5V to V CC + 0.5V DC Output Source or Sink Current (I O) ±50 mA DC V CC or Ground Current per Output Pin (I CC or IGND) ±50 mA Storage Temperature (T STG) −65˚C to +150˚C Junction Temperature (T J) CDIP 175˚C Recommended Operating Conditions Supply Voltage (V CC) AC 2.0V to 6.0V ACT 4.5V to 5.5V Input Voltage (V I) 0VtoV CC Output Voltage (V O) 0VtoV CC Operating Temperature (T A) 54AC/ACT −55˚C to +125˚C Minimum Input Edge Rate ( ∆V/∆t) AC Devices V IN from 30% to 70% of VCC V CC @ 3.3V, 4.5V, 5.5V 125 mV/ns Minimum Input Edge Rate ( ∆V/∆t) ACT Devices V IN from 0.8V to 2.0V V CC @ 4.5V, 5.5V 125 mV/ns Note 2: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, output/input loading variables. Fairchild does not recommend operation of FACT™ circuits outside databook specifications.
