MCP65R41/6  
3 µA Comparator with Integrated Reference Voltage  
Features  
Description  
• Factory Set Reference Voltage  
- Available Voltage: 1.21V and 2.4V  
- Tolerance: ±1% (typical)  
The Microchip Technology Inc. MCP65R41/6 family of  
push-pull and open-drain output comparators are  
offered with integrated Reference Voltages of 1.21V  
and 2.4V. This family provides ±1% (typical) tolerance  
while consuming 2.5 µA (typical) current. These  
comparators operate with a single-supply voltage as  
low as 1.8V to 5.5V, which makes them ideal for low  
cost and/or battery powered applications.  
• Low Quiescent Current: 2.5 µA (typical)  
• Propagation Delay: 4 µs with 100 mV overdrive  
• Input Offset Voltage: ±3mV (typical)  
• Rail-to-Rail Input: VSS - 0.3V to VDD + 0.3V  
• Output Options:  
These comparators are optimized for low power,  
single-supply applications with greater than rail-to-rail  
input operation. The output limits supply current surges  
and dynamic power consumption while switching. The  
internal input hysteresis eliminates output switching  
due to internal noise voltage, reducing current draw.  
The MCP65R41 output interfaces to CMOS/TTL logic.  
The open-drain output device MCP65R46 can be used  
as a level-shifter from 1.6V to 10V using a pull-up  
resistor. It can also be used as a wired-OR logic.
