description
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
ground, V
CC+
or V
CC–
. Offset balancing and
strobe capabilities are available, and the outputs
can be wire-OR connected. If the strobe is low, the
output will be in the off state regardless of the
differential input.
The LM111 is characterized for operation over the
full military range of –55
°
C to 125
°
C. The LM211
is characterized for operation from –40
°
C to
85
°
C, and the LM311 is characterized for
operation from 0
°
C to 70
°
C.
