5 / 7 page 5 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. Recommended Operating Conditions Note 2: CL = 15 pF, RL = 280Ω, TA = 25°C and VCC = 5V. Note 3: CL = 50 pF, RL = 280Ω, TA = 25°C and VCC = 5V. Note 4: Applies only to the DM74S163 which has synchronous clear inputs. Note 5: Applies only to the DM74S161 which has asynchronous clear inputs.
