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.
