3 / 7 page 3 www.fairchildsemi.com Absolute Maximum Ratings(Note 1) Note 1: 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. DM74S373 Recommended Operating Conditions Note 2: CL = 15 pF, RL = 280Ω, TA = 25°C and VCC = 5V. Note 3: CL = 50 pF and RL = 280Ω, TA = 25°C and VCC = 5V. Note 4: The symbol ( ↓) indicates the falling edge of the clock pulse is used for reference. Note 5: TA = 25°C and VCC = 5V. DM74S373 Electrical Characteristics over recommended operating free air temperature (unless otherwise noted) Note 6: All typicals are at VCC = 5V, TA = 25°C. Note 7: Not more than one output should be shorted at a time, and the duration should not exceed one second.
