Operating Temperature Ranges
0 to 70°C (IQXO-149)
–40 to 85°C (IQXO-149I)
Storage Temperature Range
–55 to 125°C
Tri-state Operation
No connection or Logic ‘1’ to pin 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
