VI = VCC or 0
B Port
VI = VCC or 0
Note 6: All typical values are at VCC = 3.3V, VCCQ = 3.3V, and TA = 25°C.
Note 7: For conditions shown as Min or Max, use the appropriate value specified under recommended operating conditions.
Note 8: This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
