■ MAXIMUM INPUT CURRENT : 150nA

■ MAXIMUM OFFSET CURRENT : 20nA

■ DIFFERENTIAL INPUT VOLTAGE RANGE :

±30V

■ POWER CONSUMPTION :135mW AT ±15V

■ SUPPLY VOLTAGE : +5V TO ±15V

■ OUTPUT CURRENT : 50mA

DESCRIPTION

The LM111, LM211, LM311 are voltage compara-

tors that have low input currents.

They are also designed to operate over a wide

range of supply voltages : from standard ±15V op-

erational 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 outputs currents as high as 50mA.
