- - + + MCP6566/6R/7/9 1.8V Low Power Open-Drain Output Comparator Features Description Propagation Delay at 1.8V : The Microchip Technology, Inc. MCP6566/6R/7/9 fam- DD ilies of Open-Drain output comparators are offered in - 56 ns (typical) High to Low single, dual and quad configurations. Low Quiescent Current: 100 A (typical) These comparators are optimized for low power 1.8V, Input Offset Voltage: 3 mV (typical) single-supply applications with greater than rail-to-rail Rail-to-Rail Input: V - 0.3V to V + 0.3V SS DD input operation. The internal input hysteresis eliminates Open-Drain Output output switching due to internal input noise voltage, Wide Supply Voltage Range: 1.8V to 5.5V reducing current draw. The open-drain output of the Available in Single, Dual, and Quad MCP6566/6R/7/9 family requires a pull up resistor and it supports pull-up voltages above and below V Packages: SC70, SOT-23-5, SOIC, MSOP, DD TSSOP which can be used to level shift. The output toggle frequency can reach a typical of 4 MHz (typical) while limiting supply current surges and dynamic power con- Typical Applications sumption during switching. Laptop computers This family operates with single supply voltage of 1.8V Mobile Phones to 5.5V while drawing less than 100 A/comparator of Hand-held Electronics quiescent current (typical).
