1.1 Introduction

The Texas Instruments ULN20003ADYYEVM is an evaluation module that is used to demonstrate and showcase all of the features of the underlying ULN2003ADYY Darlington Transistor Arrays. This evaluation board provides a seamless way to connect power supplies to the collector inputs of the device and turn on and off the device using the base control pins of the chip. Pull-down resistors on the base control channels make sure the control signal is never floating. Jumpers are included to short input channels together for increased current capability. Refer to the Maximum Collector Current vs Duty Cycle plots in the ULN200x, ULQ200x High-Voltage, High-Current Darlington Transistor Arrays data sheet to determine the maximum collector current given the number of outputs conducting simultaneously.
