ULN2804A Darlington transistor array
₦390.00
In stock (can be backordered)
The ULN2801A, ULN2802A, ULN2803A and
ULN2804A each contain eight Darlington
transistors with common emitters and integral
suppression diodes for inductive loads. Each
Darlington features a peak load current rating of
600 mA (500 mA continuous) and can withstand
at least 50 V in the OFF state. Outputs may be
paralleled for higher current capability.
Four versions are available to simplify interfacing
to standard logic families: the ULN2801A is
designed for general purpose applications with a
current limit resistor; the ULN2802A has a 10.5
k input resistor and Zener for 14-25 V PMOS;
the ULN2803A has a 2.7 k input resistor for 5 V
TTL and CMOS; the ULN2804A has a 10.5 k
input resistor for 6-15 V CMOS.
All types are supplied in an 18-lead plastic DIP
with a copper lead form and feature the
convenient input-opposite-output pinout to
simplify board layout.
