HIGH-VOLTAGE, HIGH-CURRENT
DARLINGTON ARRAY
Integrating seven high-voltage, high-current npn Darlingtons into
a monolithic power array, the ULN7003A AND ULN7003LW are
designed for interfacing between TTL or CMOS logic and a variety of
peripheral loads. The seven open-collector Darlington outputs are
specified for 135 V minimum breakdown and 90 V minimum sustain-
ing. Included are integral power diodes for switching inductive loads.
Typical applications include relays, lamps, print heads and hammers,
solenoids, and level shifting to power discretes.
The ULN7003A/LW include input current-limiting resistors
compatible with the drive capabilities of TTL and (most) CMOS
operating at a nominal logic supply of 5 V. Operation with 12 V
CMOS may require additional input current limiting.
The high sustaining voltage rating of this power array makes it
ideal for inductive load applications where Zener diode flyback tech-
niques are used. The increased flyback voltage provides a much faster
inductive load turn-off current decay that is especially useful with
dc stepper motors, solenoids, and print heads.

(SOIC) are electrically identical and share a
common terminal number assignment.

Output current may be limited by duty cycle,
number of drivers operating, ambient tem-
perature, and heat sinking. Under any set of
conditions, do not exceed the specified maximum
current rating or a junction temperature of 150°C.

FEATURES
Both devices are pinned with outputs opposite inputs to facilitate
ease of circuit board layout. The ULN7003A is supplied in a 16-pin
plastic dual in-line package with a copper lead frame to maximize
device power dissipation capabilities. The ULN7003LW is furnished
in a 16-lead small-outline wide-body package for surface-mount
applications.
