EIGHT DARLINGTON ARRA YS
DIP18
DESCRIPTION
The ULN2 801A -ULN2 805A each contai n e ight da rlington transistors with common emitters and integral suppression diodes for inductive loads. Each
darlington features a peak load current rating of
600mA (500mA continuous) and can withstand at
least 50V in the off st ate. Output s may b e paralle led
for higher cu rr ent c apability.
Five vers i ons ar e available to s im pl if y interfacing to
standard logi c famil ies : the ULN2 801 A is des igned
for general purpos e a pplications with a cur ren t li mi t
resistor ; the ULN2 802A has a 10.5kΩ input res istor
and zener for 14 -25V PM OS ; the U LN280 3A ha s a
2.7kΩ input resistor for 5V TTL and CMOS ; the
ULN2804A has a 10.5kΩ input resistor for 6-15V
CMOS and the ULN2805A is designed to sink a
minimum of 350mA for standard and Schot tky TT L
where higher out p ut curr ent is re quired.
All types are supplied in a 18-lead plastic DIP with
a copper lea d from and feature t he convenient inp utopposite -ou tput pin out to si m plif y boa rd lay out .
