NOTES:
1. All typical values are measured at T_amb = 25 °C and at V_CC = 1.8 V, 2.5 V, 3.3 V.
AC WAVEFORMS FOR V_CC = 3.0 V TO 3.6 V RANGE
V_M = 0.5 V_CC
V_X = V_OL + 0.300 V
V_Y = V_OH – 0.300 V
V_OL and V_OH are the typical output voltage drop that occur with the
output load.
V_I = V_CC
AC WAVEFORMS FOR V_CC = 2.3 V TO 2.7 V AND
V_CC < 2.3 V RANGE
V_M = 0.5 V_CC
V_X = V_OL + 0.15 V
V_Y = V_OH – 0.15 V
V_OL and V_OH are the typical output voltage drop that occur with the
output load.
