VM = 1.5 V at 2.7 V ≤ VCCB ≤ 3.6 V;
VM = 0.5VCCA at VCCA ≥ 4.5 V.
VOL and VOH are typical output voltage drops that occur with the output load.

VM = 1.5 V at 2.7 V ≤ VCCB ≤ 3.6 V;
VM = 0.5VCCA at VCCA ≥ 4.5 V.
VX = VOL + 0.3 V at VCCB ≥ 2.7 V;
VY = VOH − 0.3 V at VCCB ≥ 2.7 V.
VOL and VOH are typical output voltage drops that occur with the output load.
