Product data sheet Rev. 4 — 10 June 2013 5 of 21 NXP Semiconductors 74HC273; 74HCT273 Octal D-type flip-flop with reset; positive-edge trigger 6. Functional description [1] H = HIGH voltage level; h = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition; L = LOW voltage level; l = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition; X = don’t care; = LOW-to-HIGH clock transition. 7. Limiting values [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] For DIP20 package: above 70 C the value of P tot derates linearly with 12 mW/K. [3] For SO20 package: above 70 C the value of P tot derates linearly with 8 mW/K. For SSOP20 and TSSOP20 packages: above 60 C the value of P tot derates linearly with 5.5 mW/K. For DHVQFN20 packages: Ptot derates linearly with 4.5 mW/K above 60 C. Table 3.
