PIN DESCRIPTIONS
Descriptions of the pins are listed in Table 3-1.
3.1
Analog Inputs
The comparator non-inverting and inverting inputs are
high-impedance CMOS inputs with low bias currents.
3.2
CS Digital Input
This is a CMOS, Schmitt-triggered input that places the
part into a low-power mode of operation.
3.3
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.
3.4
Power Supply (VSS and VDD)
The positive power supply pin (VDD) is 1.6V to 5.5V
higher than the negative power supply pin (VSS). For
normal operation, the other pins are at voltages
between VSS and VDD.
Typically, these parts are used in a single (positive)
supply configuration. In this case, VSS is connected to
ground and VDD is connected to the supply. VDD will
need a local bypass capacitor (typically 0.01 F to
0.1F) within 2mm of the VDD pin. These can share a
bulk capacitor with nearby analog parts (within
100 mm), but it is not required.
