Quiescent supply current

VCC = 3.6V; Outputs High, VI = GND or VCC, IO = 0

VCC = 3.6V; Outputs Low, VI = GND or VCC, IO = 0

∆ICC

Additional supply current per

input pin2

VCC = 3V to 3.6V; One input at VCC -0.6V,

Other inputs at VCC or GND

NOTES:

1. All typical values are at VCC = 3.3V 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. Unused pins at VCC or GND.

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

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