FHC5MOCS T-R2I-STATE ENABLE/DISABLE OSCILLATOR
The F5C-2 Clock Oscillator employs a tri-state function for control of
the output. Applying a logic '1' to pin 1 enables the oscillator output
and a logic '0' to pin 1 disables the output to a high impedance state
called High Z state. This allows for testing by automated test
equipment by having the part appear as removed from the circuit.
The package is all metal with pin 7 as case ground which provides
shielding to help minimize EMI radiation.
