NOTES:
1. All typical values are at V

= 3.3V and T
amb
= 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 input holds the input below the specified V
level.
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 V
exceeds V
CC
allowing 5.5V on the input terminal.
7. For I/O ports the parameter I
OZ
includes the input leakage current.
