    Hello Wesley,

    The ULN2003A is an established part that has a long history of reliability and has a simple yet powerful design. Was there specifically a parameter that you were interested in comparing with a competing device?

    Hello Wesley,

    It's biggest lure is that it is so simple to use and that it is a mature product that has a robust history across many different designs. It has a few key differentiators such as an integrated free-wheeling diode to help drive inductive loads (which are frequently seen in appliances) and a variety of good packaging options, however one of its biggest attractions its simplicity.
