DESCRIPTION  

The WD2001 is a monolithic high voltage and high current Darlington transistor arrays. It consists of three  

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 WD2001 has a 2.7k  

series base resistor for each darlington pair for operation directly with TTL or 5V CMOS devices.
