Description
The Microchip Technology Inc. MCP6541/2/3/4 family
of comparators is offered in single (MCP6541), single
with chip select (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 MCP6541/2/3/4
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.
