DESCRIPTION
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 2.7kseries base resistor for each
darlington pair for operation directly with TTL or 5V CMOS
devices.
DIP-16
FEATURES
* 500mA rated collector current(Single output)
* High-voltage outputs: 50V
* Inputs compatibale with various types of logic.
* Relay driver application
