M-959
Absolute Maximum Ratings
DC Supply Voltage
6.0 V
Any Input Voltage Relative to V_DD
Any Input Voltage Relative to V_SS
Operating Temperature Range
+0.3 V

* Exceeding these ratings may permanently damage the M-959.
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.
Specifications
V_DD - V_SS = 2.5 through 6.0 V unless otherwise noted.
