(Absolute Maximum Ratings)

(Note 1)

Supply Voltage (Vcc) -0.5V to +7.0V

DC Input Diode Current (Iik) -20 mAVi = -0.5V +20 mAVi = Vcc +0.5V

DC Input Voltage (Vi) -0.5V to Vcc +0.5V

DC Output Diode Current (Iok) -20 mAVo = -0.5V +20 mAVo = Vcc +0.5V

DC Output Voltage (Vo) -0.5V to Vcc +0.5V

Note 1: Absolute maximum ratings are those values beyond which damage to the device may

occur. The databook specification 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 recommend operation of FACT TM circuits outside

databook specifications.
