Notes:

1. Value limited to 4.6V maximum..

2.To ensure proper device operation, all unused device inputs must be held at the associated VCC or GND.

3. Typical values are measured at VCC = 3.3V, TA = 25°C

4. For I/O ports, the parameter IOZ includes the input leakage current.

5. This is the increase in supply current for each input that is at one of the specified TTL voltage levels rather than at 0 or the associated VCC.
