EIGHT DARLINGTON ARRAYS EIGHTDARLINGTONS WITHCOMMON EMIT-
TERS. OUTPUT CURRENTTO 500mA. OUTPUT VOLTAGE TO50V. INTEGRAL SUPPRESSION DIODES. VERSIONS FOR ALL POPULAR LOGIC FAMI-
LIES. OUTPUT CANBE PARALLELED. INPUTS PINNED OPPOSITE OUTPUTS TO
SIMPLIFY BOARD LAYOUT
DESCRIPTIONThe ULN2801A-ULN2805Aeach contain eight dar-
lington transistors with common emitters and inte-
gral suppression diodesfor inductive loads. Each
darlington featuresa peak load current ratingof
600mA (500mA continuous) and can withstandat
least50V intheoff state. Outputsmaybe paralleled
for higher current capability.
Fiveversionsare availableto simplifyinterfacingto
standard logic families:the ULN2801Ais designed
for generalpurpose applicationswitha current limit
resistor;the ULN2802Ahas a10.5kΩ inputresistor
and zenerfor 14-25VPMOS; theULN2803Ahasa
2.7kΩ input resistorfor5V TTL and CMOS;the
ULN2804A hasa 10.5kΩ input resistorfor 6-15V
CMOS andthe ULN2805Ais designedto sinka
minimumof 350mAfor standardand SchottkyTTL
wherehigher output currentis required.
All typesare suppliedina 18-lead plastic DIP with copperleadfromandfeaturethe convenientinput-
opposite-outputpinoutto simplifyboard layout.
