Description
The SJ-C1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SJ-C1440 units with a logic “1" or open enables its pin 3 output. In the disabled mode, pin 3 presents a high impedance to the load.
