Description
Normal operation; data is high.
Normal operation; data is low.
Input unpowered. Outputs are in the default high state.
Outputs return to input state within 1 μs of V
See the pin function descriptions (Table 19 through Table 21) for more
details.
Output unpowered. Output pins are in high impedance state.
Outputs return to input state within 1 μs of V
See the pin function descriptions (Table 19 through Table 21) for more
details.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
