It 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. Standard logic families work well. If mechanical switches were 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 serial input register is loaded asynchronously with parallel digital inputs (D0-D5). When LE is high, 6-bit parallel data is transferred to the attenuator. For all modes of operations, attenuation state will stay constant while LE is kept low.

The LE (Latch Enable) must be at a logic high to control the attenuator in this manner. Latched Parallel Mode - The attenuation state is selected using the Control Voltage Inputs 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. Power-Up States PUP Truth Table If LE is set to logic LOW at power-up, the logic state of PUP1 and PUP2 determines the power-up state of the part per PUP truth table. If the LE is set to logic HIGH at power-up, the logic state of D0-D5 determines the power-up state of the part per truth table. The DVGA latches in the desired power-up state approximately 200 ms after power-up.
