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

[2] The bus hold circuit is switched off when VI > VCC allowing 5.5 V on the input terminal.

[3] Valid for data inputs only. Control inputs do not have a bus hold circuit.

[4] The specified sustaining current at the data input holds the input below the specified VI level.

[5] The specified overdrive current at the data input forces the data input to the opposite logic input state.
