High Current/Voltage Darlington Drivers
General Description
The DS2003 is comprised of seven high voltage, high current
NPN Darlington transistor pairs. All units feature common
emitter, open collector outputs. To maximize their effective-
ness, 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 op-
erating 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 capability of
a single output may be accommodated by paralleling the out-
puts.
Features
■Seven high gain Darlington pairs
■High output voltage (VCE = 50V)
■High output current (IC = 350 mA)
■TTL, PMOS, CMOS compatible
■Suppression diodes for inductive loads
■Extended temperature range

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 VCE (Sat) = 1.6V at 70°C with a pulse width of 20 ms and a duty cycle
of 30%.
Note 4: The II(OFF) current limit guaranteed against partial turn-on of the output.
Note 5: The VI(ON) voltage limit guarantees a minimum output sink current per the specified test conditions.
