3PEAK TP2011-TR

The push-pull output comparators feature the lowest nano-power (250nA maximum) and fast 13μs response time capability, allowing operation from 1.6V to 5.5V. Input common-mode range to supply rails makes them an ideal choice for power-sensitive, low-voltage (2-cell) applications. The push-pull output supports rail-to-rail output swing and interfaces with TTL /CMOS logic, and are capable of driving heavy DC or capacitive loads. The internal input hysteresis eliminates output switching due to internal input noise voltage, reducing current draw. The output limits supply current surges and dynamic power consumption while switching. Beyond the rails input and rail-to-rail output characteristics allow the full power-supply voltage to be used for signal range. Micro-sized packages provide options for portable and space-restricted applications. The related comparators with an open-drain output. Used with a pull-up resistor, these devices can be used as level-shifters for any desired voltage up to 10V and in wired-OR logic.
