Description
The SC-C1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible
signals for bus connected systems. Supplying Pin 1 of the SC-C1440 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.
