Note 2: 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.

The DM74AS74 is a dual edge-triggered flip-flops. Each flip-flop of DM74AS74  has individual D, clock, clear and preset inputs, and also complementary Q and Q outputs.

Information at input D is transferred to the Q output on the positive going edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive going pulse. When the clock input is at either the HIGH or LOW level, the D input signal has no effect.

Asynchronous preset and clear inputs will set or clear Q output respectively upon the application of LOW level signal.
