Features
Description
The LM111, LM211, LM311 are voltage
comparators that have low input currents.
They are also designed to operate over a wide
range of supply voltages: from standard ±15V
operational amplifier supplies down to the single
+5V supply used for IC logic.
Their output is 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.
