LM111 . . . JG PACKAGE
LM211, LM311 . . . D, DB, P, OR PW PACKAGE
The LM111, LM211, and LM311 are single
high-speed voltage comparators. These devices
are designed to operate from a wide range of
power supply voltages, including ±15-V supplies
for operational amplifiers and 5-V supplies for
logic systems. The output levels are compatible
with most TTL and MOS circuits. These
comparators are capable of driving lamps or
relays and switching voltages up to 50 V at 50 mA.
All inputs and outputs can be isolated from system
ground. The outputs can drive loads referenced to

LM311Y chip information
This chip, when properly assembled, displays characteristics similar to the LM311. Thermal compression or
ultrasonic bonding may be used on the doped-aluminum bonding pads. Chips may be mounted with conductive
epoxy or a gold-silicon preform.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
