Outline Diagrams
The diagrams at the right show the two package
styles that the ELM329 is available in.
ELM329P
7.24
The first shows our ELM329P product in what is
commonly called a ‘300 mil skinny DIP package’. It is
used for through hole applications.
The ELM329SM package shown at right is also
sometimes referred to as 300 mil, and is often called
an SOIC package. We have chosen to simply refer to
it as an SM (surface mount) package.
The drawings shown here provide the basic
dimensions for these ICs only. Please refer to the
