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.

ULN2003ADR2G Product Overview

The ULN2003ADR2G is a 50V Darlington Transistor Driver Array for driving relays or incandescent lamps. The seven NPN Darlington connected transistors in these arrays are well suited for driving lamps, relays or printer hammers in a variety of industrial and consumer applications. Their high breakdown voltage and internal suppression diodes insure freedom from problems associated with inductive loads. Peak inrush currents to 500mA permit them to drive incandescent lamps. The ULN2003A with a 2.7kR series input resistor is well suited for systems utilizing a 5V TTL or CMOS Logic.
