Explanation / Answer

VIL is the maximum voltage on digital Input pin that can be considered as a low i.e. digital zero.

VIH is the smallest voltage on digital Input pin that can be considered as a high i.e. digital one.

Given Vcc =5V

From the Data sheet ,

VIL = 0.3Vcc = 1.5V ;

VIH = 0.6Vcc = 3.0V;
