3 www.fairchildsemi.com DM74174 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: TA = 25°C and VCC = 5V.

Electrical Characteristics

over recommended operating free air temperature range (unless otherwise noted) Note 3: All typicals are at VCC = 5V, TA = 25°C. Note 4: Not more than one output should be shorted at a time. Note 5: With all outputs open and all DATA and CLEAR inputs at 4.5V, ICC is measured after a momentary ground, then 4.5V applied to the CLOCK input.
