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 outputs are VIT (0.5 VDD) and VOT (0.5 VDD). Input rise and fall times (10% ↔ 90%) are <5 ns.
Note: VIT - VINPUT Test
VOT - VOUTPUT Test
VIHT - VINPUT HIGH Test
