掳C.

2. For bushold parts, the bushold circuit is switched off when V

I

> V

CC

allowing 5.5 V on the input pin.

3. Valid for data inputs of bushold parts (74LVCH16244A) only. For data inputs only, control inputs do not have a

bushold circuit.

4. The specified sustaining current at the data inputs holds the input below the specified V

I

level.

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