MCP6547-E/MS

MCP6547-E/MS is a dual open-drain output sub-microamp comparator. The outputs are open-drain and are capable of driving heavy DC or capacitive loads. This comparator is optimized for low-power, single-supply application with greater than rail-to-rail input operation. The output limits supply current surges and dynamic power consumption while switching. The open-drain output family can be used as a level-shifter for up to 10V using a pullup resistor. It can also be used as a wired-OR logic. The internal input hysteresis eliminates output switching due to internal noise voltage, reducing current draw. Application includes laptop computers, mobile phones, metering systems, handheld electronics, RC timers, alarm and monitoring circuits, windowed comparators, multivibrators.
