描述 Description

The SH-B1480 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SH-B1480 units with a logic “1 or open enables its Pin 4 output. In the disable mode, Pin 4 presents a high impedance to the load.
