MCP6561T-E/LT

MCP6561T-E/LT is a 1.8V low-power push-pull output comparator. This comparator is 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 push-pull output of the device family supports rail-to-rail output swing and interfaces with CMOS/TTL logic. The output toggle frequency can reach a typical of 4MHz while limiting supply current surges and dynamic power consumption during switching. This family operates with a single-supply voltage of 1.8V to 5.5V, while drawing less than 100 µA/comparator of quiescent current (typical). Applications include laptop computers, mobile phones, handheld electronics, RC timers, alarm and monitoring circuits, window comparators, and multivibrators.
