74ABT16244A
16-bit buffer/line driver; 3-state
6. Functional description
[1] H = HIGH voltage level;
L = LOW voltage level;
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.
