16.2 Maximum Ratings
(Voltage referenced to V
SS
)
Rating
1.
Only one output shorted for a time.
Stresses above those listed as ‘maximum ratings’ may cause permanent
damage to the device. This is a stress rating only and functional
operation of the device at these conditions is not implied. Exposure to
maximum rating conditions for extended periods may affect device
reliability.
This device contains circuitry to protect the inputs against damage due
to high static voltages or electric fields; however, it is advised that normal
precautions be taken to avoid application of any voltage higher than
maximum-rated voltages to this high-impedance circuit. For proper
operation, it is recommended that VIN and VOUT be constrained to the
range VSS
≤
(VIN or VOUT)
≤
VDD. Unused inputs are connected to the
appropriate voltage level, either VSS or VDD.
Positive current flow is defined as conventional current flow into the
device. Negative current flow is defined as current flow out of the device.
