The Tversion 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. Output Tri-State (Pin 1 High*) Disable (Pin 1 Low) Frequency Output High Z State Internal Osc. Oscillates Oscillates Current Lower than Normal Normal * When PIN 1 is allowed to float, it is held high by an internal pull-up resistor.
