NOTE:
1. These typical values are at VCC = 3.3V and Tamb = 25°C.
AC WAVEFORMS
VM = 1.5 V at VCC w 2.7 V
VM = 0.5 S VCC at VCC < 2.7 V
VOL and VOH are the typical output voltage drop that occur with the output load.
VX = VOL + 0.3 V at VCC ≥ 2.7 V
VX – VOL + 0.1 ⋅ VCC at VCC < 2.7 V
VY = VOH – 0.3 V at VCC ≥ 2.7 V
VY = VOH – 0.1 ⋅ VCC at VCC < 2.7 V
