+ + MCP6541/1R/1U/2/3/4 Push-Pull Output Sub-Microamp Comparators Features Description Low Quiescent Current: 600 nA/Comparator (typ.) The Microchip Technology Inc. MCP6541/1R/1U/2/3/4 family of comparators is offered in single (MCP6541, Rail-to-Rail Input: V - 0.3V to V + 0.3V SS DD MCP6541R, MCP6541U), single with Chip Select (CS) CMOS/TTL-Compatible Output (MCP6543), dual (MCP6542) and quad (MCP6544) Propagation Delay: 4 s configurations. The outputs are push-pull (CMOS/TTL- (typical, 100 mV Overdrive) compatible) and are capable of driving heavy DC or Wide Supply Voltage Range: 1.6V to 5.5V capacitive loads. Available in Single, Dual and Quad These comparators are optimized for low-power, Single Available in SOT-23-5, SC-70-5 * Packages single-supply operation with greater than rail-to-rail Chip Select (CS) with MCP6543 input operation. The push-pull output of the Low Switching Current MCP6541/1R/1U/2/3/4 family supports rail-to-rail out- put swing and interfaces with TTL/CMOS logic. The Internal Hysteresis: 3.3 mV (typ.) internal input hysteresis eliminates output switching Temperature Ranges: due to internal input noise voltage, reducing current - Industrial: -40C to +85C draw. The output limits supply current surges and - Extended: -40C to +125C dynamic power consumption while switching. This product family operates with a single-supply voltage as Typical Applications low as 1.6V and draws less than 1 A/comparator of quiescent current. Laptop Computers The related MCP6546/7/8/9 family of comparators from Mobile Phones Microchip has an open-drain output. Used with a pull- Metering Systems up resistor, these devices can be used as level-shifters Hand-held Electronics for any desired voltage up to 10V and in wired-OR RC Timers logic.
