All typical values are at VCC = 3.3V and Tamb = 25°C. AC WAVEFORMS VM = 1.5V at VCC w 2.7V; VM = 0.5 VCC at VCC t 2.7V. VOL and VOH are the typical output voltage drop that occur with the output load. VX = VOL + 0.3V at VCC w 2.7V; VX = VOL + 0.1 VCC at VCC t 2.7V VY = VOH –0.3V at VCC w 2.7V; VY = VOH – 0.1 VCC at VCC t 2.7V SW00116 An INPUT VM tPHL tPLH VOL VI VM GND VOH Yn OUTPUT Waveform 1.
