MCP6566/6R/6U/7/9  
1.8V Low Power Open-Drain Output Comparator  
Features  
Description  
• Propagation Delay at 1.8VDD  
:
The Microchip Technology, Inc. MCP6566/6R/6U/7/9  
families of Open-Drain output comparators are offered  
in single, dual and quad configurations.  
- 56 ns (typical) High to Low  
• Low Quiescent Current: 100 µA (typical)  
• Input Offset Voltage: ±3 mV (typical)  
• Rail-to-Rail Input: VSS - 0.3V to VDD + 0.3V  
• Open-Drain Output  
These comparators are optimized for low power 1.8V,  
single-supply applications with greater than rail-to-rail  
input operation. The internal input hysteresis eliminates  
output switching due to internal input noise voltage,  
reducing current draw. The open-drain output of the  
MCP6566/6R/6U/7/9 family requires a pull up resistor  
and it supports pull-up voltages above and below VDD  
which can be used to level shift. The output toggle  
frequency can reach a typical of 4 MHz (typical) while  
limiting supply current surges and dynamic power  
consumption during switching.  
• Wide Supply Voltage Range: 1.8V to 5.5V  
• Available in Single, Dual, and Quad  
• Packages: SC70, SOT-23-5, SOIC, MSOP,  
TSSOP  
Typical Applications  
• Laptop computers  
• Mobile Phones  
This family operates with single supply voltage of 1.8V  
to 5.5V while drawing less than 100 µA/comparator of  
quiescent current (typical).  
• Hand-held Electronics  
• RC Timers  
Package Types  
• Alarm and Monitoring Circuits  
• Window Comparators  
• Multi-vibrators
