The Microchip Technology Inc. MCP6541/1R/1U/2/3/4 family of comparators is designed for low-power, single-supply operation. These comparators feature push-pull (CMOS/TTL-compatible) outputs capable of driving heavy DC or capacitive loads. They are optimized with rail-to-rail input operation and internal hysteresis to reduce current draw and improve stability. Typical applications include laptop computers, mobile phones, metering systems, and alarm circuits.
