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.
