Notes
1. All typical values are measured at VCC = 3.3 V and Tamb = 25 °C.
2. For bushold parts, the bushold circuit is switched off when VI > VCC allowing 5.5 V on the input terminal.
3. For I/O ports the parameter IOZ includes the input leakage current.
4. Valid for data inputs of bushold parts (74LVCH16245A) only.
5. For data inputs only, control inputs do not have a bushold circuit.
6. The specified sustaining current at the data input holds the input below the specified VI level.
7. The specified overdrive current at the data input forces the data input to the opposite input state.
