Absolute Maximum Ratings (T
A = 25°C)
Absolute maximum ratings are those values beyond which the device
could be permanently damaged. Absolute maximum ratings are stress
ratings only and functional device operation is not implied.

Important Note:
All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are at the
specified temperature and are pulsed tests, therefore: TJ = TC = TA.
Electrical Characteristics
VS = ±5V, VSD = 5V, RL = 2.3k, CL = 15pF, TA = 25°C, unless otherwise specified.
