TheULN2801A-ULN2805Aeachcontaineightdar­lingtontransistorswith 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
least50Vintheoffstate.Outputsmaybeparalleled

Fiveversionsareavailableto simplifyinterfacingto
standardlogicfamilies: the ULN2801Aisdesigned
forgeneralpurposeapplicationswitha currentlimit
resistor; theULN2802Ahasa 10.5kΩinputresistor
andzenerfor14-25VPMOS; theULN2803Ahas 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 of350mA for standardandSchottkyTTL
