16-bit edge-triggered D-type flip-flop; 3-state
7. Functional description
7.1 Function table
[1] H = HIGH voltage level;
h = HIGH voltage level one setup time prior to the HIGH-to-LOW clock transition;
L = LOW voltage level;
l = LOW voltage level one setup time prior to the HIGH-to-LOW clock transition;
NC = no change;
X = don’t care;
Z = high-impedance OFF-state;
↑ = LOW-to-HIGH clock transition.
8. Limiting values
[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.
