Absolute Maximum Ratings
Storage Temperature
-55° to 125° C
Operating Ambient Temperature
-25° to 70° C
Operating Ambient Temperature
for the M-991-02SM
-40° to 85° C
VDD 7.0V
Any Input Voltage
VSS -0.6 to VDD +0.6V
Note:
1. Exceeding these ratings may permanently damage the M-991.
Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the opera-
tional sections of this data sheet is not implied. Exposure of
the device to the absolute maximum ratings for an extend-
ed period may degrade the device and effect its reliability.
