standard model - Highest and Lowest $SU(3)_F$ states


For the finite dimensional $(p,q)$-irreducible representation of $SU(3)_F$, we can label the states as $\mid T_3,Y\rangle$. Where $T_3$ is the third component of isospin and $Y$ is the hypercharge. How can I obtain the highest and Lowest weight states? I mean what are the $T_3$ and $Y$ values?
