ELECTRICAL CHARACTERISTICS (continued)
(V
CC
= +2.5V to +11V, T
A
= T
MIN
to T
MAX
, unless otherwise noted. Typical values are at T
A
= +25°C.)
Note 1:
The voltage-detector output remains in the correct state for V
CC
down to 1.2V when V
IN
≤
V
CC
/ 2.
Note 2:
Supply current has a monotonic dependence on V
CC
(see Typical Operating Characteristics).
Note 3:
IN leakage current has a monotonic dependence on V
CC
(see Typical Operating Characteristics).
Note 4:
The MAX834 open-drain output can be pulled up to a voltage greater than V
CC
, but may not exceed 11V.
