The TMUX6211, TMUX6212, and TMUX6213 are complementary metal-oxide semiconductor (CMOS) switches with four independently selectable 1:1, single-pole, singlethrow (SPST) switch channels. The devices work well with dual supplies (±4.5 V to±18 V), a single supply (4.5 V to 36 V), or asymmetric supplies (such as VDD = 12 V, VSS = –5 V). The TMUX621x supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from VSS to VDD.
The switches of the TMUX6211 are turned on with Logic 0 on the appropriate logic control inputs, while Logic 1 is required to turn on switches in the TMUX6212. The four channels of the TMUX6213 are split with two switches supporting Logic 0, while the other two switches support Logic 1. The TMUX6213 exhibits break-before-make switching, allowing the device to be used in cross-point switching applications.
The TMUX621x are part of the precision switches and multiplexers family of devices. These devices have very low on and off leakage currents and low charge injection, allowing them to be used in high precision measurement applications.
