Description

The Microchip Technology Inc. MCP6546/6R/6U/7/8/9 family of comparators is offered in single (MCP6546, MCP6546R, MCP6546U), single with chip select (CS) (MCP6548), dual (MCP6547) and quad (MCP6549) 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 of the MCP6546/6R/6U/7/8/9 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. 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 from Microchip has a push-pull output that supports rail-torail output swing and interfaces with CMOS/TTL logic.
