    | Partname: | SCA1421 |  | Description: | 3.3 V, +/-50 ppm,  CMOS crystal clock oscillator |  | Manufacturer: |  |  | Package: | SMD |  | Pins: | 4 |  | Oper. temp.: | 0 to 70 |  | Datasheet: | PDF (276K). Click here to download *)
 |  | The SC-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-1420 units with a logic "1" or open enables its Pin 3 output. In the disable mode, Pin 3 presents a high impedance to the load. |  |  Click here to download SCA1421 Datasheet*)
