Product data sheet Rev. 03 — 23 March 2010 5 of 17 NXP Semiconductors 74ABT823 9-bit D-type flip-flop with reset and enable; 3-state 6. Functional description 6.1 Function table [1] H = HIGH voltage level; L = LOW voltage level; h = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition; I = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition; ↑ = LOW-to-HIGH clock transition; NC = no change; X = don’t care; Z = high-impedance OFF-state. 7. Limiting values [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C. Table 3.
