Power-Up States Using the Parallel PUP truth table the attenuator can be turned on at a specific attenuation state. By using the PUP1 and PUP2 line four different attenuation states can be selected. It can also be used in the Direct Parallel Mode using the Control Voltage Inputs to select attenuation values.
