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

VILT - VINPUT LOW Test
