LM119JAN
High Speed Dual Comparator
General Description
The LM119is a precision high speed dual comparator fabri-cated on a single monolithic chip.It is designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground.Further,it has higher gain and lower input currents than devices such as the LM710.The uncommitted collector of the output stage makes the LM119compatible with RTL,DTL and TTL as well as capable of driving lamps and relays at currents up to 25mA.
Although designed primarily for applications requiring opera-tion from digital logic supplies,the LM119is fully specified for power supplies up to ±15V.It features faster response than the LM111at the expense of higher power dissipation.How-ever,the high speed,wide operating voltage range and low package count make the LM119much more versatile than older devices such as the LM711.

Note1:Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.Operating Ratings indicate conditions for which the device is functional,but do not guarantee specific performance limits.For guaranteed specifications and test conditions,see the Electrical Characteristics.The guaranteed specifications apply only for the test conditions listed.Some performance characteristics may degrade when the device is not operated under the listed test conditions.
Note2:The maximum power dissipation must be derated at elevated temperatures and is dictated by
T Jmax(maximum junction temperature),θJA(package junction to ambient thermal resistance),and T A(ambient temperature).The maximum allowable power dissipation at any temperature is P Dmax=(T Jmax-T A)/θJA or the number given in the Absolute Maximum Ratings,whichever is lower.
Note3:For supply voltages less than±15V the absolute maximum input voltage is equal to the supply voltage.
Note4:Human Body model,1.5KΩin series with100pF.
Note5:K=V/mV.
