请参考 PDF 数据表获取器件具体的封装图。
The SN74LVC1G18 can be used to select between controlling two analog switches. In this use case, pull-down resistors are connected to both outputs of the SN74LVC1G18 to ensure that a valid state is available for the inputs to the switches at all times. This defaults the switches into the "off" state to prevent unwanted data transmission.
