SC-A1449-FREQ中文资料NEL数据手册PDF规格书

描述 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.
