MCP6546/6R/6U/7/8/9 family 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 are capable of driving heavy DC or capacitive loads. These comparators are optimized for low power, single-supply application with greater than rail-to-rail input operation. The output limits supply current surges and dynamic power consumption while switching. The open-drain output of the MCP6546/6R/6U/7/8/9 family can be used as a level-shifter for up to 10V using a pull- up resistor. It can also be used as a wired-OR logic. The internal Input hysteresis eliminates output switch- ing due to internal noise voltage, reducing current draw. These comparators operate with a single-supply voltage as low as 1.6V and draw a quiescent current of less than 1 µA/comparator. The related MCP6541/2/3/4 family of comparators from Microchip has a push-pull output that supports rail-to- rail output swing and interfaces with CMOS/TTL logic. * SC-70-5 E-Temp parts are not available at this release of the data sheet. MCP6546U SOT-23-5 is E-Temp only.
