These comparators are optimized for low power, singlesupply 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 singlesupply voltage as low as 1.6V and draws less than 1 A/ 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.
