8.1 Overview

The TMUX550x are a family of analog multiplexers. Section 8.2 provides a top-level block diagram of both the TMUX5508 and TMUX5509. The TMUX5508 is an eight-channel, single-ended, analog mux. The TMUX5509 is a four-channel, differential or dual 4:1, single-ended, analog mux. Each channel is turned on or turned off based on the state of the address lines and enable pin.
