2 MCP6546/6R/6U/7/8/9family of comparators, 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 arecapable of driving heavy DC or capacitive comparators are optimized for low power,single-supply application with greater than rail-to-railinput operation. The Output limits supply current surgesand dynamic power consumption while switching. Theopen-drain Output of the MCP6546/6R/6U/7/8/9 familycan be used as a level-shifter for up to 10V using a pull-up resistor. It can also be used as a wired-OR internal Input hysteresis eliminates Output switch-ing due to internal noise voltage, reducing current comparators operate with a single-supplyvoltage as low as and draw a quiescent current ofless than 1 related MCP6541/2/3/4 family of comparators fromMicrochip has a push-pull Output that supports rail-to-rail Output swing and interfaces with CMOS/TTL logic.
