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.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.

The 74LVQ74 is a dual D-type flip-flop with Asynchronous Clear and Set inputs and complementary (Q, Q) outputs. Information at the input is transferred to the outputs on the positive 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. After the Clock Pulse input threshold voltage has been passed, the Data input is locked out and information present will not be transferred to the outputs until the next rising edge of the Clock Pulse input.

Asynchronous Inputs of the 74LVQ74:
   LOW input to S_D (Set) sets Q to HIGH level
   LOW input to C_D (Clear) sets Q to LOW level
   Clear and Set are independent of clock
   Simultaneous LOW on C_D and S_D makes both
   Q and Q HIGH
