[1] All typical values are measured at VCC = 3.3 V and Tamb = 25 °C.
[2] For valid test results, data must not be loaded into the flip-flops (or latches) after applying 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] This parameter is valid for VCC = 0 V to 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to 3.3 V ± 0.3 V. A transition time
of 100 µs is permitted. This parameter is valid for Tamb = 25 °C only.
[6] ICC is measured with outputs pulled to VCC or GND.
[7] This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
