3 Description

The TMUX861x is a 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 dual supplies, a single supply, or asymmetric supplies up to a maximum supply voltage of 100V. The TMUX861x devices provide consistent analog parametric performance across the entire supply voltage range. The TMUX861x family supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins.

All logic inputs support logic levels of 1.8V, 3.3V, and 5V and can be connected as high as 48V, 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.
