Texas Instruments TMUX821x SPST Four-Channel Switches are modern high-voltage capable analog switches with latch-up immunity. Each device has four independently controllable 1:1, single-pole, single-throw (SPST) switch channels. The devices work well with single, dual, or asymmetric supplies up to a supply voltage of 100V (max.). The TMUX821x devices provide consistent analog parametric performance across the entire supply voltage range. The TMUX821x family supports bidirectional digital and analog signals on the drain (Dx) and source (Sx) pins.
