The serial control interrface is activated when P/S is kept high. The 6-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, 6-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. When P/S is low, 3-wire SPI interface inputs (SERIN, CLK, LE) are disabled and the input register is loaded with parallel digital inputs (D0-D5). When LE is high, 6-bit parallel data changes the state of the part per truth table. Typ.

Direct Parallel Mode - The attenuation state is changed by the control voltage inputs D0-D5 directly. The LE (Latch Enable) must be at a logic high at all times to control the attenuator in this manner. Latched Parallel Mode - The attenuation state is selected using the control voltage inputs D0-D5 and set while the LE is in the Low state. The attenuator will not change state while LE is Low. Once all Control Voltage Inputs are at the desired states the LE is pulsed. See timing diagram above for reference. Information furnished by Analog Devices is believed to be accurate and reliable.
