VM = 1.5 V at VCC ≥ 2.7 V;

VM = 0.5 × VCC at VCC < 2.7 V.

VOL and VOH are typical output voltage drop that occur with the output load.

VM = 1.5 V at VCC ≥ 2.7 V;

VM = 0.5 × VCC at VCC < 2.7 V.

VX = VOL + 0.3 V at VCC ≥ 2.7 V;

VX = VOL + 0.1 V at VCC < 2.7 V.

VY = VOH − 0.3 V at VCC ≥ 2.7 V;

VY = VOH − 0.1 V at VCC < 2.7 V.

VOL and VOH are typical output voltage drop that occur with the output load.
