Supply Voltage (VCC) DC Input Diode Current (IIK) VI = - 0.5V VI = VCC + 0.5V DC Input Voltage (VI) DC Output Diode Current (IOK) VO = - 0.5V VO = VCC + 0.5V DC Output Voltage (VO) DC Output Source or Sink Current (IO) DC VCC or Ground Current per Output Pin (ICC or IGND) Storage Temperature (TSTG) - 0.5V to +7.0V - 20 m A +20 m A - 0.5V to VCC + 0.5V - 20 m A +20 m A - 0.5V to VCC + 0.5V Junction Temperature (TJ) CDIP 175˚C Remended Operating Conditions Supply Voltage (VCC) ’AC Input Voltage (VI) Output Voltage (VO) Operating Temperature (TA) 54AC Minimum Input Edge Rate (∆V/∆t) ’AC Devices VIN from 30% to 70% of VCC VCC @ 3.3V, 4.5V, 5.5V 2.0V to 6.0V 0V to VCC 0V to VCC - 55˚C to +125˚C ± 50 m A ± 50 m A - 65˚C to +150˚C 125 m V/ns Note 1: 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, and output/input loading variables. National does not remend operation of FACT™ circuits outside databook specifications.
