(over operating temperature range)
Operating Temperature Range
▪▪ 0 to 70°C (CFPS-302, -303)
▪▪ –40 to 85°C (CFPS-302I, -303I)
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
Environmental
