Storage Temperature Range
Tri-state Operation (CFPS-303, -303I)
No connection or Logic ‘1’ to pin 1 enables oscillator output
Logic ‘0’ to pin 1 disables oscillator output; when disabled the
oscillator output goes to the high impedance state
Maximum ‘pull-down’ resistance required to disable output
= 20kΩ
Disable current 50µA typical
Terminal Strength: 0.91kg max force perpendicular to top and
bottom
Hermetic Seal: not to exceed 1x10

Solderability: MIL-STD-202E, Method 208C
Vibration: 10 to 55Hz 0.76mm displacement, sweep 60
seconds, duration 2 hours

Temperature Range: 10 cycles
Shock: 981m/s
