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. MCP6541/1R/1U/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 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 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  
• Alarm and Monitoring Circuits  
• Windowed Comparators  
• Multi-vibrators  
* SC-70-5 E-Temp parts not available at this release of  
the data sheet.  
MCP6541U SOT-23-5 is E-Temp only.
