DS2003
High Current/Voltage Darlington Drivers
General Description
The DS2003 is comprised of seven high voltage, high cur-
rent NPN Darlington transistor pairs. All units feature com-
mon emitter, open collector outputs. To maximize their effec-
tiveness, these units contain suppression diodes for
inductive loads and appropriate emitter base resistors for
leakage.
The DS2003 has a series base resistor to each Darlington
pair, thus allowing operation directly with TTL or CMOS oper-
ating at supply voltages of 5.0V.
The DS2003 offers solutions to a great many interface
needs, including solenoids, relays, lamps, small motors, and
LEDs. Applications requiring sink currents beyond the capa-
bility of a single output may be accommodated by paralleling
the outputs.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of "Electrical Characteristics" provide conditions for actual device operation.
Note 2: All limits apply to the complete Darlington series except as specified for a single device type.
Note 3: Under normal operating conditions these units will sustain 350 mA per output with V
CE (Sat)
= 1.6V at 70C with a pulse width of 20 ms and a duty cycle of
30%.
Note 4: The I
I(OFF)
current limit guaranteed against partial turn-on of the output.
Note 5: The V
I(ON)
voltage limit guarantees a minimum output sink current per the specified test conditions.
