... Pin 1 must always be low to prevent the attenuator from entering an unknown state. Power-up Control Settings The DAT-15575-PN always assumes a specifiable attenuation setting on power-up, allowing a known at- tenuation state to be established before an initial parallel control word is provided. When the attenuator powers up with LE=0, the control bits are automatically set to one of two possible values ...
