Absolute Maximum Ratings*
Operating Temperature Range .......... OOC to + 70°C
Storage Temperature Range ........ -55°C to + 150°C
Positive Voltage on any I/O Pin, with respect to ground ...
................................. +7.0V
Negative Voltage on any I/O Pin, with respect to ground
................................. -0.3V
Power Dissipation . . . . . . . . . . . . . . . . . . . . . . . 0.75W
Note: When powering this device from laboratory or
system power supplies, it is important that the Absolute
Maximum Ratings not be exceeded or device failure can
result. Some power supplies exhibit voltage spikes or
"glitches" on their outputs when the AC power is siwtched
on and off. In addition, voltage transients on the AC power
line may appear on the DC output.
Comments*
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device.
These are stress ratings only. Functional operation of
this device at these or any other conditions above those
indicated .in the operational sections of this specification
is not implied and exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
