Description
The Microchip MCP6546/6R/6U/7/8/9 family of com-
parators, is offered in single (MCP6546, MCP6546R,
MCP6546U), single with Chip Select (CS) (MCP6548),
dual (MCP6547) and quad (MCP6549) configurations.
The outputs are open-drain and are capable of driving
heavy DC or capacitive loads.
These comparators are optimized for low-power,
single-supply application with greater than rail-to-rail
input operation. The output limits supply current surges
and dynamic power consumption while switching. The
open-drain output of the MCP6546/6R/6U/7/8/9 family
can be used as a level-shifter for up to 10V using a pull-
up resistor. It can also be used as a wired-OR logic.
The internal input hysteresis eliminates output switch-
ing due to internal noise voltage, reducing current draw.
These comparators operate with a single-supply
voltage as low as 1.6V and draw a quiescent current of
less than 1 µA/comparator.
The related Microchip MCP6541/2/3/4 family of com-
parators has a push-pull output that supports rail-to-rail
output swing and interfaces with CMOS/TTL logic.
Note that SC-70-5 E-Temp parts are not available at
this release of the data sheet.
The MCP6546U SOT-23-5 is E-Temp only.

3.0 PIN DESCRIPTIONS
Descriptions of the pins are listed in Table 3-1.
3.1 Analog Inputs
The comparator noninverting 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, open-drain digital
outputs. They are designed to make level shifting and
wired-OR easy to implement.
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 (V
SS). For
normal operation, the other pins are at voltages
between VSS and VDD, except the output pins which
can be as high as 10V above V
SS.
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 pins can
share a bulk capacitor with nearby analog parts (within
100 mm), but it is not required.
