MCP6541/2/3/4 family of comparators is offered in single (MCP6541, 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. The push-pull output of the MCP6541/1R/1U/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 inter- nal input noise voltage, reducing current draw. The out- put limits supply current surges and dynamic power consumption while switching. This product family oper- ates 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. * SC-70-5 E-Temp parts not available at this release of the data sheet.
