Features (Typical unless otherwise noted) • Operates at +2.7V, +3V, +3.3V, +5V • Low Power consumption <9.45 mW @ V+ = 2.7V (max) • Fast Response Time of 180 ns Description The LM6511 voltage comparator is ideal for analog-digital interface circuitry when only a +3V or +3.3V supply is available. The open-collector output permits signal compatibility with a wide variety of digital families: +5V CMOS, +3V CMOS, TTL and so on. Supply voltage may range from 2.7V to 36V between supply voltage leads. The LM6511 operates with little power consumption (Pdiss < 9.45 mW at V+ = +2.7V and V- = 0V). This voltage comparator offers many features that are available in traditional sub-microsecond comparators: output sync strobe, inputs and output may be isolated from system ground, and wire-ORing. Also, the LM6511 uses the industry-standard, single comparator pinout configuration. Applications • Portable Equipment • Cellular Phones • Digital Level Shifting

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
