MCP6561T-E/OT Low Power Push Pull Comparator, SOT-23, 5 Pins

The MCP6561T-E/OT is a low-power, push-pull output comparator from Microchip, engineered for 1.8V single-supply applications. It features greater than rail-to-rail input operation, ensuring accurate signal detection across the full supply range. Its internal input hysteresis effectively eliminates output switching caused by internal input noise voltage, reducing unnecessary current draw and enhancing stability.

With a typical propagation delay of just 47ns, this comparator is ideal for high-speed signal processing. The push-pull output supports rail-to-rail output swing and interfaces seamlessly with CMOS and TTL logic, simplifying integration into digital systems. It can achieve a typical output toggle frequency of 4MHz while minimising supply current surges and dynamic power consumption during switching.

Key specifications include a low quiescent current of 100μA (typical), an input offset voltage of ±3mV (typical), and a supply voltage range of 1.8V to 5.5V. The device comes in a compact SOT-23 package with 5 pins, suitable for surface mount applications. It operates over a wide temperature range from -40°C to 125°C and is AEC-Q100 qualified for automotive use.
