ULN2003B (ACTIVE)

High-voltage High-current Darlington Transistor Array

 

Description

The ULN2003B device is a high-voltage, high-current Darlington transistor array. This device consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500 mA. The Darlington pairs can be paralleled for higher current capability.

The ULN2003B has a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or CMOS devices.

Features

  • Greater Than 4x Reduction in Output Leakage (ICEX) over ULN2003A
  • 500-mA Rated Collector Current (Single Output)
  • High-Voltage Outputs 50 V
  • Output Clamp Diodes
  • Inputs Compatible With Various Types of Logic
  • Relay-Driver Applications
