Enable/Disable Functional Description
Under normal operation the Enable/Disable is left open, or set to a logic high state, and the VCC4 is
oscillating. When the E/D is set to a logic low, the oscillator stops and the output is in a high impedance
state. This helps reduce power consumption as well as facilitating board testing and troubleshooting.
TriState Functional Description
Under normal operation the Tristate is left open or set to a logic high state. When the Tri-State is set to a
logic low, the oscillator remains active but the output buffer is in a high impedance state. This helps facilitate
board testing and troubleshooting.
