AC test inputs are driven at VIHT (0.9 VDD) for a logic "1" and VILT(0.1 VDD) for a logic "0".
Measurement reference points for inputs and outpputs are VIT(0.5 VDD) and VOT(0.5 VDD). Input
rise and fall time (10% - 90% ) is <5ns
Note: VIT = Vinput Test
VOT = Voutput Test
VIHT = Vinput HIGH Test
VILT = Vinput LOW Test
