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.
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.

A Zener diode can be used to increase the flyback
voltage. This gives a much faster inductive load turn-
OFF current decay. The maximum Zener voltage plus
the load supply voltage plus the internal diode forward
voltage must not exceed the device’s rated sustaining
voltage.
