DESCRIPTION The LM111, LM211 and LM311 are voltage comparators that have low input currents. They are also designed to operateover a wide range of supplyvoltages : from standard ±15V operational amplifier supplies down to the single +5V supply used for IC logic. Their outputis compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages up to +50V at output currents as high as 50mA. PIN CONNECTIONS (top view)
