AC test inputs are driven at VIHT (0.9VDD) for a logic “1” and VILT (0.1VDD) for a logic “0”. Measurement reference points

for inputs and outputs are VHT (0.6VDD) and VLT (0.4VDD). Input rise and fall times (10% ↔ 90%) are <5 ns.

Note: VHT - VHIGH Test

VLT - VLOW Test

VIHT - VINPUT HIGH Test

VILT - VINPUT LOW Test
