ULN2003ADR Product Overview

The ULN2003ADR is a seven high-voltage/high-current NPN Darlington Transistor Array. All units feature a common emitter and open collector outputs. To maximize their effectiveness, these units contain suppression diodes for inductive loads. The ULN2003ADR device has a series base resistor to each Darlington pair, thus allowing operation directly with TTL or CMOS operating at supply voltages of 5V or 3.3V. The ULN2003ADR device 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 outputs.

Output Clamp Diodes
Inputs Compatible With Various Types of Logic
250ns Typical Delay Time

Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
