• Manufacturer Part Number: MCP6542
• Description: Push-pull Output Sub-microamp Comparators
• Manufacturer: Microchip Technology Inc.

3.0
Descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
3.1
The comparator non-inverting and inverting inputs are
high-impedance CMOS inputs with low bias currents.
3.2
This is a CMOS, Schmitt-triggered input that places the
part into a low power mode of operation.
3.3
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.

Typically, these parts are used in a single (positive)
supply configuration. In this case, V
ground and V
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the V
bulk capacitor with nearby analog parts (within
100 mm), but it is not required.
