... The Microchip Technology Inc. MCP6541/1R/1U/2/3/4 family of comparators is offered in single (MCP6541, + 0.3V 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 ...
