ENABLE/DISABLE OPTIONS (T/N)
Statek offers two enable/disable options: T and N. The T-
version has a Tri-State output and oscillates 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 T.
