Statek offers two enable/disable options: E and N. The E-
version has a Tri-State output and stops oscillating internally
when the output is put into the high Z state. The N-version
does not have PIN 1 connected internally and so has no
enable/disable capability. The following table describes the
Enable/Disable option E.
