MCP6541/1R/1U/2/3/4  
Push-Pull Output Sub-Microamp Comparators  
Description  
Features  
• Low Quiescent Current: 600 nA/comparator (typ.)  
• Rail-to-Rail Input: VSS - 0.3V to VDD + 0.3V  
• CMOS/TTL-Compatible Output  
The Microchip Technology Inc. MCP6541/2/3/4 family  
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 or  
capacitive loads.  
• Propagation Delay: 4 µs (typ., 100 mV Overdrive)  
• Wide Supply Voltage Range: 1.6V to 5.5V  
• Available in Single, Dual and Quad  
• Single available in SOT-23-5, SC-70-5 * packages  
• Chip Select (CS) with MCP6543  
• Low Switching Current  
These comparators are optimized for low power, single-  
supply operation with greater than rail-to-rail input  
operation.  
The  
push-pull  
output  
of  
the  
MCP6541/1R/1U/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 inter-  
nal input noise voltage, reducing current draw. The out-  
put limits supply current surges and dynamic power  
consumption while switching. This product family oper-  
ates with a single-supply voltage as low as 1.6V and  
draws less than 1 µA/comparator of quiescent current.  
• Internal Hysteresis: 3.3 mV (typ.)  
• Temperature Ranges:  
- Industrial: -40°C to +85°C  
- Extended: -40°C to +125°C  
Typical Applications  
• Laptop Computers  
• Mobile Phones  
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.  
• Metering Systems  
• Hand-held Electronics  
• RC Timers  
* SC-70-5 E-Temp parts not available at this release of  
the data sheet.  
• Alarm and Monitoring Circuits  
• Windowed Comparators  
• Multi-vibrators  
MCP6541U SOT-23-5 is E-Temp only.
