Description
The Microchip Technology Inc. MCP6541/1R/1U/2/3/4
family of comparators is offered in single (MCP6541,
MCP6541R, MCP6541U), single with Chip Select (CS)
(MCP6543), dual (MCP6542) and quad (MCP6544)
configurations. The outputs are push-pull (CMOS/TTL-
compatible) and are capable of driving heavy DC or
capacitive loads.
These comparators are optimized for low power,
single-supply operation with greater than rail-to-rail
input operation. The push-pull output of the MCP6541/
1R/1U/2/3/4 family supports rail-to-rail output swing
and interfaces with TTL/CMOS logic. The internal input
hysteresis eliminates output switching due to internal
input noise voltage, reducing current draw. The output
limits supply current surges and dynamic power
consumption while switching. This product family
operates with a single-supply voltage as low as 1.6V
and draws less than 1 µA/comparator of quiescent
current.
The related MCP6546/7/8/9 family of comparators from
Microchip has an open-drain output. Used with a pull-
up resistor, these devices can be used as level-shifters
for any desired voltage up to 10V and in wired-OR
logic.
* SC-70-5 E-Temp parts not available at this release of
the data sheet.
MCP6541U SOT-23-5 is E-Temp only.
