TRISTATE/DISABLE OPTIONS (T/N)
Statek offers two enable/disable options: T and N. The T-
version has a Tri-State output and continues 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 Tri-State/Disable capability. The following table
describes the Tri-State/Disable option T.
