NOTES:

1. All typical values are at VCC = 3.3 V and Tamb = 25 °C.

2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND.

3. This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 msec. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V

a transition time of 100

µsec is permitted. This parameter is valid for Tamb = 25 °C only.

4. Unused pins at VCC or GND.

5. ICCZ is measured with outputs pulled up to VCC or pulled down to ground.

6. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.

7. This is the bus hold overdrive current required to force the input to the opposite logic state.
