Description

The SC-B1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-B1440 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.
