Notes:
1. The input and output negative voltage
ratings may be excluded if the input
and output clamp ratings are observed.
2. This current will flow only when the
output is in the high state level
V₀ >V_DDQ.
3. The package thermal impedance is
calculated in accordance with
JESD 51.
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device.These ratings
are stress specifications only and functional operation of the device at these or any other conditions above those listed in
the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect product reliability.
