AC WAVEFORMS
VCC = 2.3 TO 2.7 V RANGE
1. VM = 0.5 V
2. VX = VOL + 0.15V
3. VY = VOH – 0.15V
4. VI = VCC
5. VOL and VOH are the typical output voltage drop that occur with
the output load.
VCC = 3.0 TO 3.6 V RANGE AND VCC = 2.7 V
1. VM = 1.5 V
2. VX = VOL + 0.3V
3. VY = VOH – 0.3V
4. VI = 2.7 V
5. VOL and VOH are the typical output voltage drop that occur with
the output load.
