Product data sheet Rev. 03 — 13 May 2008 5 of 18 NXP Semiconductors 74AHC273; 74AHCT273 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 CP transition; L = LOW voltage level; l = LOW voltage level one set-up time prior to the LOW-to-HIGH CP transition; ↑ = LOW-to-HIGH; 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 SO20 packages: above 70 °C the value of P tot derates linearly at 8 mW/K. For TSSOP20 packages: above 60 °C the value of P tot derates linearly at 5.5 mW/K. For DHVQFN20 packages: above 60 °C the value of Ptot derates linearly at 4.5 mW/K. D6 17 data input D7 18 data input Q7 19 flip-flop output VCC 20 supply voltage Table 2.
