3.1 Analog Inputs
The comparator non-inverting and inverting inputs are
high-impedance CMOS inputs with low bias currents.
3.2 Digital Outputs
The comparator outputs are CMOS, push-pull digital
outputs. They are designed to be compatible with
CMOS and TTL logic and are capable of driving heavy
DC or capacitive loads.
3.3 Power Supply (V_SS and V_DD)
The positive power supply pin (V_DD) is 1.8V to 5.5V
higher than the negative power supply pin (V_SS). For
normal operation, the other pins are at voltages
between V_SS and V_DD.
Typically, these parts are used in a single (positive)
supply configuration. In this case, V_SS is connected to
ground and V_DD is connected to the supply. V_DD will
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the V_DD pin. These can share a
bulk capacitor with nearby analog parts (within
100 mm), but it is not required.
