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
