[1] All typical values are measured at VCC = 3.3 V (unless stated otherwise) 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 of bus hold parts only (74LVCH244A). Note that 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 input state.
