3.Description:The Microchip Technology Inc. MCP6541/1R/1U/2/3/4family of comparators is offered in single (MCP6541, MCP6541R, MCP6541U), single with Chip Select (CS)(MCP6543), dual (MCP6542) and quad (MCP6544)configurations. The outputs are push-pull (CMOS/TTL-compatible) and are capable of driving heavy DC orcapacitive loads.
These comparators are optimized for low-power,single-supply operation with greater than rail-to-railinput operation. The push-pull output of theMCP6541/1R/1U/2/3/4 family supports rail-to-rail out-put swing and interfaces with TTL/CMOS logic. Theinternal input hysteresis eliminates output switchingdue to internal input noise voltage, reducing currentdraw.
The output limits supply current surges anddynamic power consumption while switching. Thisproduct family operates with a single-supply voltage aslow as 1.6V and draws less than 1 μA/comparator ofquiescent current.The related MCP6546/7/8/9 family of comparators fromMicrochip has an open-drain output. Used with a pull-up resistor, these devices can be used as level-shiftersfor any desired voltage up to 10V and in wired-ORlogic.
