PACKAGING OPTIONS HGXOHT Statek offers two enable/disable options: E and N. The Eversion 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 has no enable/disable capability. The following table describes the Enable/Disable option E.
