FEATURES  
DESCRIPTION  
The ULN2803A device is a high-voltage, high-current  
Darlington transistor array. The device consists of  
eight npn Darlington pairs that feature high-voltage  
outputs with common-cathode clamp diodes for  
switching inductive loads. The collector-current rating  
of each Darlington pair is 500 mA. The Darlington  
pairs may be connected in parallel for higher current  
capability.  
500-mA-Rated Collector Current  
(Single Output)  
High-Voltage Outputs: 50 V  
Output Clamp Diodes  
Inputs Compatible With Various  
Types of Logic  
Relay-Driver Applications  
Applications include relay drivers, hammer drivers,  
lamp drivers, display drivers (LED and gas  
discharge), line drivers, and logic buffers. The  
ULN2803A device has a 2.7-kΩ series base resistor  
for each Darlington pair for operation directly with  
TTL or 5-V CMOS devices.  
Compatible with ULN2800A Series
