The 7-bit serial word must be loaded MSB first. The positive-edge sensitive CLK and LE requires clean transitions. If mechanical switches are used, sufficient debouncing should be provided. When LE is high, 7-bit data in the serial input register is transferred to the attenuator. When LE is high, CLK is masked to prevent data transition during output loading.
