The Microchip Technology Inc. MCP65R41 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. 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. This family of devices is available in the 6-lead SOT-23 package.
