EL5481C/EL5482C
Quad 8ns High-Speed Comparators
Absolute Maximum Ratings (T = 25°C)
A
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.
