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.
