• Fast Response Times

• Strobe Capability

(1) Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold-compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

The LM211-EP is a single high-speed voltage comparator. This device is 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. This comparator is 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, V

CC+

or V

CC–

. Offset balancing and strobe capabilities

are available, and the outputs can be wired-OR connected. If the strobe is low, the output is in the off state,

regardless of the differential input.
