*** An internal pullup resistor from pin 1 to pin 8 allows active output if pin 1 is left open.

The H5C-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 4 as case ground which provides
shielding to help minimize EMI radiation.
