AC WAVEFORMS FOR VCC = 3.0 V TO 3.6 V
RANGE
VM = 0.5 VCC
VX = VOL + 0.300 V
VY = VOH – 0.300 V
VOL and VOH are the typical output voltage drop that occur with the
output load.
VI = VCC
AC WAVEFORMS FOR VCC = 2.3 V TO 2.7 V AND
VCC < 2.3 V RANGE
VM = 0.5 VCC
VX = VOL + 0.15 V
VY = VOH – 0.15 V
VOL and VOH are the typical output voltage drop that occur with the
output load.
