(Plastic Package)
DESCRIPTION
The ULQ2 801A-U LQ2805A each co ntain eight darlington 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 i n the off state. Outpu ts may be parall eled
for higher c ur re nt cap abi lit y .
Five ver s ions are available t o s im p lif y in t erfa ci ng to
standard lo gic f amil ies : the UL Q2801A is desi gned
for gene ra l p ur pos e applicatio ns w it h a c ur re nt l im it
resistor ; the ULQ2802A has a 10.5k Ω input res istor
and zener for 14 -25V PMOS ; the ULQ280 3A has a
2.7kΩ input resistor for 5V TTL and CMOS ; the
ULQ2804A has a 10.5kΩ input resistor for 6-15V
CMOS and the ULQ2805A is designed to sink a
minimum of 350mA for standard and Schottky TTL
where higher output curren t i s required.
All types are supplied in a 18-lead plastic DIP with
a copper le ad f ra me and feature the convenient input-oppo si te-o ut put pinout to simpli fy bo ar d lay out.
