Texas Instruments TMUX8108/TMUX8109 Multiplexers are modern high voltage capable analog multiplexers in 8:1 (single-ended) and 4:1 (differential) configurations. The devices work well with dual supplies, a single supply, or asymmetric supplies up to a maximum supply voltage of 100V. The TMUX810x devices provide consistent analog parametric performance across the entire supply voltage range. The TMUX8108 and TMUX8109 support bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins.
All logic inputs support logic levels of 1.8V, 3.3V, 5V and can be connected as high as 48V, allowing 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 Texas Instruments TMUX8108/TMUX8109 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.
