These products are precision high speed dual
comparatorsdesignedto operateoverawiderange
of supplyvoltagesdown to a single5V logicsupply
and ground and have low input currents and high
gains.
The open collector of the output stage makes
compatible with TTL as well as capableof driving
lamps andrelays at currents upto 25mA.
Although designed primarily for applications
requiring operation from digital logic supplies, are
fully specifiedfor power suppliesup to ±15V.
Theyfeaturefasterresponsethanthe LM111atthe
expenseof higherpower dissipation. However,the
high speed, wide operatingvoltage rangeand low
packagecountmake the much more versatile.
