Overview
ULN2801A, ULN2802A, ULN2803A, ULN2804A Eight Darlington array Features ■ Eight Darlington transistors with common emitters ■ 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 Description 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; ...
