LM119/LM219/LM319
High Speed Dual Comparator
General Description
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.
The LM319A offers improved precision over the standard
LM319, with tighter tolerances on offset voltage, offset cur-
rent, and voltage gain.

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 LM119 is specified from 55C to +125C, the LM219 is
specified from 25C to +85C, and the LM319A and LM319
are specified from 0C to +70C.
