4 / 8 page www.fairchildsemi.com 4 Absolute Maximum Ratings(Note 3) Note 3: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Recommended Operating Conditions Note 4: TA = 25°C and VCC = 5V. Supply Voltage 7V Input Voltage 7V Operating Free Air Temperature Range 0 °C to +70°C Storage Temperature Range −65°C to +150°C Symbol Parameter Min Nom Max Units VCC Supply Voltage 4.75 5 5.25 V VT+ Positive-Going Input Threshold Voltage 12 V at the A Input (VCC = Min) VT− Negative-Going Input Threshold Voltage 0.8 1 V at the A Input (VCC = Min) VT+ Positive-Going Input Threshold Voltage 12 V at the B Input (VCC = Min) VT− Negative-Going Input Threshold Voltage 0.8 0.9 V at the B Input (VCC = Min) IOH HIGH Level Output Current −0.4 mA IOL LOW Level Output Current 8 mA tW Pulse Width Data 40 ns (Note 4) Clear 40 tREL Clear Release Time (Note 4) 15 ns Rate of Rise or Fall of 1 Schmitt Input (B) (Note 4) Rate of Rise or Fall of 1 Logic Input (A) (Note 4) REXT External Timing Resistor (Note 4) 1.4 100 k Ω CEXT External Timing Capacitance (Note 4) 0 1000 µF DC Duty Cycle RT = 2 kΩ 50 % (Note 4) RT = REXT (Max) 60 TA Free Air Operating Temperature 0 70 °C |
