DESCRIP TION
TheULQ2801A-ULQ2805Aeachcontaineightdarlington transistorswith 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
least50Vin theoffstate.Outputsmaybeparalleled
for highercurrent capability.
Fiveversionsare availableto simplify interfacingto
standardlogic families: theULQ2801Ais designed
for generalpurposeapplicationswitha current limit
resistor; theULQ2802Ahasa 10.5kΩinputresistor
and zenerfor14-25VPMOS; theULQ2803Ahasa
2.7kΩ input resistor for 5V TTL and CMOS ; the
ULQ2804Ahas a 10.5kΩ input resistor for 6-15V
CMOS and the ULQ2805A is designed to sink a
minimumof 350mAfor standardand SchottkyTTL
wherehigheroutput currentis required.
Alltypes are suppliedin a 18-leadplastic DIP with
a copper lead frameand feature the convenientinput-opposite-outputpinout to simplifyboard layout.
