Output High (Z) Freq. Output * Normally High (internal pull-up resistor) POWER DOWN vs TRISTATE Power Down: When Pin 1is low (0) the oscillator stops oscillation. Tristate: When Pin 1 is low the oscillator is running. However, the output buffer amplifier stops functioning and the Pin 5 output is in high impedance state.
