DC Electrical Characteristics

Notes:

2. All typical values are at VCC = 3.3V, TA = 25°C.

3. Applies to bushold versions only (74LVTH2244).

4. An external driver must source at least the specified current to switch from LOW-to-HIGH.

5. An external driver must sink at least the specified current to switch from HIGH-to-LOW.

6. This is the increase in supply current for each, input that is at the specified voltage level rather than VCC or GND.
