* Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operational sections of the specifications is not implied.
Exposure to Absolute Maximum Rating Conditions for extended periods
may affect device reliability.
ELECTRICAL CHARACTERISTICS: T_A = 25°C, unless otherwise specified.

Description
Analog input. This pin is both the power supply input and the voltage to be monitored.
Digital output. This output goes low when V_IN drops below V_{D– ET} and returns
high when V_IN rises above V^–DET + V_HYST. (See timing chart).
Ground terminal.
