The TMUX541x is a general purpose complementary metal-oxide semiconductor (CMOS) switch device with four independently selectable 1:1, single-pole, single-throw (SPST) switch channels. The device works with a single supply (4.5V to 50V), dual supplies (±4.5V to ±25V), or asymmetric supplies (such as VDD = 37.5V, VSS = –12.5V). The TMUX541x supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins ranging from VSS to VDD. The switches of the TMUX541x are controlled with appropriate logic control inputs on the SELx pins. The TMUX541x exhibits break-before-make switching, allowing the device to be used in cross-point and multiplexing applications. The TMUX541x is a part of the general purpose switches and multiplexers family of devices emphasizing uses in broad range of applications while reducing BOM cost.
