MCP6579T-E/ST Microchip 4-Channel Comparator Open Drain O/P, 40 ns 5.5 V 1.8 V 14-Pin TSSOP

The Microchip Low Power Open-Drain Output Comparator incorporate a POR feature that keeps the output high impedance until VDD rises to a sufficient voltage to control the comparator. They are optimized for low power, single supply applications with greater than rail to rail input operation. Internal input hysteresis eliminates output switching due to internal input noise voltage, resulting in reduced current draw.
