[1] All typical values are measured at VCC = 3.3 V (unless stated otherwise) and Tamb = 25 °C.
[2] For valid test results data must not be loaded into the flip-flops (or latches) after applying the power.
[3] Unused pins at VCC or GND.
[4] This is the bus hold overdrive current required to force the input to the opposite logic state.
[5] Increase in supply current for each input at the specified voltage level other than VCC or GND
