MICROCHIP MCP6547T-E/MS

The MCP6546/6R/6U/7/8/9 family of comparators is offered in single, single with chip select (CS), dual and quad configurations. The outputs are open-drain and are capable of driving heavy DC or capacitive loads. These comparators are 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 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. These comparators operate with a single-supply voltage as low as 1.6V and draw a quiescent current of less than 1 µA/comparator. The related MCP6541/2/3/4 family of comparators has a push-pull output that supports rail-to-rail output swing and interfaces with CMOS/TTL logic.
