74ALVT16823

18-bit bus-interface D-type flip-flop with reset and enable; 3-state

6. Functional description

Table 3. Function table

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;

NC = no change; X = don’t care; Z = high-impedance OFF-state;

↑ = LOW-to-HIGH clock transition; ↑ = not a LOW-to-HIGH clock transition.

[1] The input and output negative voltage ratings may be exceeded if the input and output clamp 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.
