Push Pull Output Sub Micro Amp Low Power Analogue Comparator, SMD, 1.6V to 5.5V, SOT 23, 5 Pins - 

The MCP6541T-E/OT is a push-pull output Sub-Microamp Comparator is offered in single configuration. This output is push-pull (CMOS/TTL compatible) and are capable of driving heavy DC or capacitive loads. This comparator is optimized for low-power, single-supply operation with greater than rail-to-rail input operation. The push-pull output of this 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 single-supply voltage as low as 1.6V and draws less than 1μA/comparator of quiescent current.
