LM119/LM219/LM319  
High Speed Dual Comparator  
n Operates from a single 5V supply  
General Description  
±
n Typically 80 ns response time at 15V  
n Minimum fan-out of 2 each side  
The LM119 series are precision high speed dual compara-  
tors fabricated on a single monolithic chip. They are de-  
signed to operate over a wide range of supply voltages down  
to a single 5V logic supply and ground. Further, they have  
higher gain and lower input currents than devices like the  
LM710. The uncommitted collector of the output stage  
makes the LM119 compatible with RTL, DTL and TTL as well  
as capable of driving lamps and relays at currents up to 25  
mA.  
n Maximum input current of 1 µA over temperature  
n Inputs and outputs can be isolated from system ground  
n High common mode slew rate  
Although designed primarily for applications requiring opera-  
tion from digital logic supplies, the LM119 series are fully  
±
specified for power supplies up to 15V. It features faster re-  
sponse than the LM111 at the expense of higher power dis-  
sipation. However, the high speed, wide operating voltage  
range and low package count make the LM119 much more  
versatile than older devices like the LM711.  
The LM319A offers improved precision over the standard  
LM319, with tighter tolerances on offset voltage, offset cur-  
rent, and voltage gain.  
The LM119 is specified from −55˚C to +125˚C, the LM219 is  
specified from −25˚C to +85˚C, and the LM319A and LM319  
are specified from 0˚C to +70˚C.
