ULN2803AD, ULN2803AN, ULN2804AD, ULN2804AN
8-channel Darlington current driver
(Functional equivalent of TD62083AFN, TD62084AFN Toshiba)
The ULN2803AD, ULN2803AN, ULN2804AD,
ULN2804AN are 8- channel current driver, consisting of
eight Darlington transistors.
Transistors, having high-voltage outputs with high-
current load are coupled in common-cathode circuit for
commutation of inductive load.
Collector current of one Darlington pair not ex-
ceed 500 mA. Darlington pairs can be bridged to in-
crease current.
