LM211DR

The LM111, LM211, and LM311 devices are single
high-speed voltage comparators. These devices are
designed to operate from a wide range of powersupply 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 ground, VCC+ or VCC−. Offset
balancing and strobe capabilities are available, and
the outputs can be wire-OR connected. If the strobe
is low, the output is in the off state, regardless of the
differential input.
