SS
= -12V, V
CC
= 5V ± 10%, unless otherwise specified)
NOTE 3: The algebraic convention, where the more positive (less negative) limits designated as maximum, is used in this datasheet for logic
levels only (e.g. if - 10V is a maximum, the typical value is a more negative voltage).
NOTE 4: Not more than one outputs should be shorted at one time.
