ULN2003 LINEAR INTEGRATED CIRCUIT
1
THESE HIGH-VOLTAGE,HIGH-
CURRENT
DESCRIPTION
Darlington arrays are comprised of seven silicon NPN
darlington pairs on a common monolithic substrate. All units
have open-collector outputs and integral diodes for inductive
load transient suppression.
FEATURES
* ULN2003 has a 2.7kWseries base resistor for each
darlington pair, allowing operation directly with TTL or
CMOS operating at a supply voltage of 5V. These devices
will handle numberous interface needs particularly those
beyond the capabilities of standard logic buffers.
* ULN2003 is the original high-voltage, high-current darlington
array. The output transistors are capable of sinking 500mA
and will sustain at least 50V in the off state. Output may be
paralle-led for higher load-current capability.
* ULN2003 darlington arrays are furnished in a 16-pin dual in-
line plastic package. These an also be supplyed in a
hermetic dual in-line package for use in military an
aerospace applications.
