TRISTATE/DISABLE OPTION T

FUNCTION TABLE

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.
