Note (*2).
●Active High
OE pin = "H" or "open" : Specified frequency output.
OE pin = "L" : Output is high impedance, oscillation stops.
●Active Low
OE pin = "L" or "open" : Specified frequency output.
OE pin = "H" : Output is high impedance, oscillation stops.

To maintain stable operation, provide a 0.01uF to 0.1uF
by-pass capacitor at a location as near as possible to the
power source terminal of the crystal product (between Vcc
- GND).
