DESCRIPTION
The ULN2801A-ULN2805Aeachcontain eight dar-
lington transistors with common emitters and inte-
gral suppression diodes for inductive loads. Each
darlington features a peak load current rating of
600mA (500mA continuous) and can withstand at
least50V in the off state.Outputsmaybe paralleled
for highercurrent capability.
Fiveversions are available to simplify interfacing to
standard logic families : the ULN2801A is designed
for generalpurpose applicationswith a current limit
resistor; the ULN2802Ahas a 10.5kΩ inputresistor
and zenerfor 14-25V PMOS; theULN2803A has 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 standardand Schottky TTL
wherehigher output current is required.
All types are supplied in a 18-lead plastic DIP with
a copperleadfromandfeaturetheconvenientinput-
opposite-outputpinoutto simplify board layout.
