The MCP6541/2/3/4 family of comparators is a low power, single-supply, greater than rail-to-rail input operation comparator with push-pull (CMOS/TTL-compatible) outputs capable of driving heavy DC or capacitive loads.
The MCP6541/2/3/4 family consists of single, dual and quad push‑pull output comparators with rail‑to‑rail input capability and low quiescent current. They are offered in a variety of packages (SOT‑23‑5, SC‑70‑5, PDIP, SOIC, MSOP, TSSOP) and are suited for laptop computers, mobile phones, metering systems, hand‑held electronics, RC timers, alarm and monitoring circuits, and windowed comparators.
The datasheet details electrical characteristics such as supply voltage range, input voltage range, propagation delay, short‑circuit current, and temperature specifications, as well as pin functions and typical performance curves. It also includes information on code protection, trademarks, and worldwide sales and service contacts.
| Supply Voltage (Vop) | 1.6 V – 5.5 V |
|---|---|
| Quiescent Current per comparator | 0.3 µA – 1.0 µA |
