NOTE:

1. Unless otherwise stated, 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
