Eight Darlington array  
Datasheet production data  
Eight Darlington transistors with common  
Output current to 500 mA  
Output voltage to 50 V  
Integral suppression diodes  
Versions for all popular logic families  
Output can be paralleled  
Inputs pinned opposite outputs to simplify  
board layout  
convenient input-opposite-output pinout to  
simplify board layout.  
The ULN2801A, ULN2802A, ULN2803A and  
ULN2804A each contain eight Darlington  
transistors with common emitters and integral  
suppression diodes for inductive loads. Each  
Darlington features a peak load current rating of  
600 mA (500 mA continuous) and can withstand  
at least 50 V in the OFF state. Outputs may be  
paralleled for higher current capability.  
Four versions are available to simplify interfacing  
to standard logic families: the ULN2801A is  
designed for general purpose applications with a  
current limit resistor; the ULN2802A has a 10.5  
kΩ input resistor and Zener for 14-25 V PMOS;  
the ULN2803A has a 2.7 kΩ input resistor for 5 V  
TTL and CMOS; the ULN2804A has a 10.5 kΩ  
input resistor for 6-15 V CMOS.  
All types are supplied in an 18-lead plastic DIP  
with a copper lead form and feature the  
Table 1.
