Product data sheet Rev. 2 — 21 April 2015 5 of 19 Nexperia 74AHC74-Q100; 74AHCT74-Q100 Dual D-type flip-flop with set and reset; positive-edge trigger 6. Functional description [1] H = HIGH voltage level; L = LOW voltage level; = LOW to HIGH transition; Qn+1 = state after the next LOW to HIGH CP transition; X = don’t care. 7. Limiting values [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] For SO14 packages: above 70 C the value of P tot derates linearly at 8 mW/K. For TSSOP14 packages: above 60 C the value of P tot derates linearly at 5.5 mW/K. For DHVQFN14 packages: above 60 C the value of P tot derates linearly at 4.5 mW/K. Table 3.
