GENERAL DESCRIPTION
The ADG5208F and ADG5209F are 8:1 and dual 4:1 analog multiplexers. The ADG5208F switches one of eight inputs to a common output, and the ADG5209F switches one of four differential inputs to a common differential output. An EN input on both devices enables or disables the device. Each channel conducts equally well in both directions when on, and each channel has an input signal range that extends to the supplies. The digital inputs are compatible with 3 V logic inputs over the full operating supply range.
