[1] All typical values for VCC = 2.5 V ± 0.2 V are measured at VCC = 2.5 V and Tamb = 25 °C.

All typical values for VCC = 3.3 V ± 0.3 V 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 parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms.

From VCC = 1.2 V to (2.5 ± 0.2) V a transition time of 100 μs is permitted. This parameter is valid for Tamb = 25 °C only.

[5] ICC with outputs disabled is measured with outputs pulled to VCC or GND.

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

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

[8] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms.

From VCC = 1,2 V to (3.3 ± 0.3) V a transition time of 100 μs is permitted. This parameter is valid for Tamb = 25 °C only.
