as a buffer circuit... means whenever u need a high current....
e.x-> if u wnat to run a 12V relay using a PC parallel port(DB-25) output, u kan use such a TTL IC.... if u just connect the relay it will never switch!! the current in a parallel port output will just be enough to light 2 series LEDs....
ULN**** ICs are used in circuits that use PIC ICs(micro controller)..... Also ULN**** series ICs has low power dissipation...

The ULN2003 is a monolithic high voltage and high current
Darlington transistor arrays. It consists of seven NPN darlington
pairs that features high-voltage outputs with common-cathode
clamp diode for switching inductive loads. The collector-current
rating of a single darlington pair is 500mA. The darlington pairs
may be parrlleled for higher current capability. Applications include
relay drivers,hammer drivers, lampdrivers,display drivers(LED gas
discharge),line drivers, and logic buffers.
The ULN2003 has a 2.7kΩ series base resistor for each
darlington pair for operation directly with TTL or 5V CMOS
devices.

Do the integrated circuit and the microchip go together?
An integrated circuit can be either monolithic (all on one piece of semiconductor) or hybrid (several separate components attached to a tiny ceramic circuit board). A microchip is another name for a monolithic integrated circuit.
