Push-Pull Output Sub-Microamp Comparators  
Features  
Description  
• 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), 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 µA/  
comparator of quiescent current.  
• Propagation Delay 4 µs (typ.)  
• 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  
• Internal Hysteresis: 3.3 mV (typ.)  
• Industrial Temperature: -40°C to +85°C  
Typical Applications  
• Laptop Computers  
• Mobile Phones  
• Metering Systems  
• Hand-held Electronics  
• RC Timers  
• Alarm and Monitoring Circuits  
• Windowed Comparators  
• Multi-vibrators  
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.
