The TMUX8211, TMUX8212 and TMUX213 are modern high voltage capable analog switches with latch-up immunity. Each device has four independently selectable 1:1, single-pole, single-throw (SPST) switch channels. The devices work well with dual supplies, a single supply, or asymmetric supplies up to a maximum supply voltage of 100 V. The TMUX821x family supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins.

All logic inputs support logic levels of 1.8 V, 3.3 V, 5  V and can be connected as high as 48 V, allowing for system flexibility with control signal voltage. Fail-safe logic circuitry allows voltages on the logic pins to be applied before the supply pin, protecting the device from potential damage.

The device family provides latch-up immunity, preventing undesirable high current events between parasitic structures within the device. A latch-up condition typically continues until the power supply rails are turned off and can lead to device failure. The latch-up immunity feature allows this family of multiplexers to be used in harsh environments.
