Notes:

7. All typical values are at VCC = 3.3V, VCCQ = 5.0V, and TA = 25°C

8. For conditions shown as Max. or Min., use the appropriate value specified under recommended operating conditions.

9. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V CC or GND.
