MCP6541/2/3/4

Description

The Microchip Technology Inc. MCP6541/2/3/4 family

of comparators is offered in single (MCP6541), single

with chip select (MCP6543), dual (MCP6542) and quad

(MCP6544) configurations. The outputs are push-pull

(CMOS/TTL-compatible) and are capable of driving

heavy DC or capacitive loads.

These comparators are optimized for low power, single-

supply operation with greater than rail-to-rail input

operation. The push-pull output of the MCP6541/2/3/4

family supports rail-to-rail output swing and interfaces

with TTL/CMOS logic. The internal input hysteresis

eliminates output switching due to internal input noise

voltage, reducing current draw. The output limits supply

current surges and dynamic power consumption while

switching. This product family operates with a single-

supply voltage as low as 1.6V and draws less than 1 碌A/

comparator of quiescent current.

The related MCP6546/7/8/9 family of comparators from

Microchip has an open-drain output. Used with a pull-up

resistor, these devices can be used as level-shifters for

any desired voltage up to 10V and in wired-OR logic.
