PIN DESCRIPTIONS

Descriptions of the pins are listed in Table 3-1.

TABLE 3-1:

PIN FUNCTION TABLE

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, open-drain digital

outputs. They are designed to make level shifting and

wired-OR easy to implement.

3.3

Power Supply (VSS and VDD)

The positive power supply pin (VDD) is 1.8V 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 µF to

0.1 µF) within 2 mm of the VDD pin. These can share a

bulk capacitor with nearby analog parts (within

100 mm), but it is not required.
