MCP6/R/U/2// family of comparators is offered in single (MCP6, MCP6R, MCP6U), single with Chip Select (CS) (MCP6), dual (MCP62) and quad (MCP6) configurations. The outputs are pushpull (CMOS/TTLcompatible) and are capable of driving heavy DC or capacitive loads. These comparators are optimized for low power, singlesupply operation with greater than railtorail input operation. The pushpull output of the MCP6/ R/U/2// family supports railtorail output swing and interfaces with TTL/CMOS logic. 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. This product family operates with a singlesupply voltage as low as.6v and draws less than µa/comparator of quiescent current. The related MCP66/7/8/9 family of comparators from Microchip has an opendrain output. Used with a pullup resistor, these devices can be used as levelshifters for any desired voltage up to 0V and in wiredor logic. * SC70 ETemp parts not available at this release of the data sheet.
