STMicroelectronics ULN2003 NPN Darlington Array 7 Outputs 50V 500mA DIP16

The STMicroelectronics ULN2003 Darlington Array is a seven-channel NPN driver IC rated at 50V and 500mA, designed to interface low-level logic with high-power loads.

Each of the seven open collector Darlington pairs uses common emitters. The outputs can drive inductive loads such as relays, stepper motors and DC brushed motors, and integrated suppression diodes help protect the device from voltage spikes generated by these loads. The outputs can be paralleled to increase current handling for heavier applications.

Key Features

• Seven open collector Darlington pairs with common emitters
• Integrated suppression diodes for inductive loads
• Outputs can be paralleled for higher current
• Inputs compatible with TTL, CMOS, PMOS and DTL logic levels
• Input pins positioned opposite the output pins to simplify PCB layout
• DC current gain (hFE) of 1000
• Through-hole DIP16 package

Specifications

• Transistor polarity: NPN
• Collector emitter voltage (V(br)ceo): 50V
• DC collector current: 500mA
• Number of outputs: 7
• Operating temperature maximum: 85°C
• Mounting: Through-hole

Applications

The device can drive lamps, LEDs, gas discharge displays and relays, and can also be used as a line driver. It suits industrial and electronic control systems where a logic-level input must switch a higher-power load. The DIP16 through-hole format makes it straightforward to prototype and assemble on a PCB.
