OUTLINE & DIMENSIONS
DESCRIPTION
XO22 ultra-miniature oscillators consist of a TTL/CMOS-compatible
hybrid circuit and a miniature quartz crystal packaged in a low-profile,
industry-standard ceramic package. The package provides a fully
specified clock oscillator with a very small footprint.

XO22. Output (Pad 3) is active if Pad 1
not connected or Pad 1 is 'HIGH'.
Output high impedance when 'LOW'
or GROUND is applied to Pad 1.
