INTEGRATED CIRCUITS AU211/LM111/211/311/311B Voltage comparator Product data Supersedes data of 2001 Aug 03 2003 Sep 30 Philips Semiconductors Philips Semiconductors Product data Voltage comparator AU211/LM111/211/311/311B DESCRIPTION The LM111 series are voltage comparators that have input currents approximately a hundred times lower than devices like the A710. They are designed to operate over a wider range of supply voltages; from standard ±15 V op amp supplies down to a single 3 V supply. Their output is compatible with RTL, DTL, and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50 V at currents as high as 50mA. Both the inputs and the outputs of the LM111 series can be isolated from system ground, and the output can drive loads referred to ground, the positive supply, or the negative supply. Offset balancing and strobe capability are provided and outputs can be wire-ORed. Although slower than the A710 (200 ns response time versus 40 ns), the devices are also much less prone to spurious oscillations. The LM111 series has the same pin configuration as the A710 series.
