Eagle parts: Assorted 74xxx logic ICs in TSSOP packages

Posted on Tuesday, July 17th, 2012 in Eagle parts by DP

For the DP Badge project we used some tiny TSSOP logic ICs, including the ULN2003 (pictured above) , 74HC595, 74HC4017, and the 555 timer. Previews from our Eagle part library are blow the fold.

74HC595 Serial shift register.

74HC4017 decade counter and encoder.

555 universal timer IC in SOIC-8.

  1. I have 2 questions.

    First, why did you make your power and ground pins separate from your actual device when you created your symbol.

    Second, do you typically allow the value to be adjusted (Value = On) when creating your device.

    The basis for that question is that amongst the many struggles I have with Eagle is making the BOM as accurate as possible, bearing in mind that small differences in Part #’s may equate to no change in footprint.
