DESCRIPTION
The LM319 series are precision high-speed dual comparators
fabricated on a single monolithic chip. They are designed 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
A710. The uncommitted collector of
the output stage makes the LM319 compatible 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 operation from
digital logic supplies, the LM319 series are fully specified for power
supplies up to
15V. It features faster response than the LM111 at
the expense of higher power dissipation. However, the high-speed,
wide operating voltage range and low package count make the
LM319 much more versatile than older devices like the
A711.
FEATURES
Two independent comparators
Operates from a single 5V supply
Typically 80ns response time at
15V
Minimum fanout of 3 (each side)

2. The offset voltages and offset currents given are the maximum values required to drive the output to within 1V of either supply with a 1mA
load. Thus these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
