NOTES:
1. All typical values are at VCC = 3.3V and Tamb = 25°C.
2. Valid for data inputs of bushold parts (LVCH-A) only.
3. For data inputs only, control inputs do not have a bushold circuit
4. The specified sustaining current at the data inputs do not have a bushold circuit.
5. The specified overdrive current at the data input forces the data input to the opposite logic input state.
6. For bushold parts, the bushold circuit is switched off when VI exceeds VCC allowing 5.5V on the input terminal.
