Description
The Microchip Technology Inc. MCP6541/2/3/4 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 inter-
nal input noise voltage, reducing current draw. The out-
put limits supply current surges and dynamic power
consumption while switching. This product family oper-
ates 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.
