100-V, flat RON, 1:1 (SPST), four-channel switches with latch-up immunity and 1.8V logic (logic low)

The TMUX8211, TMUX8212, and TMUX8213 are 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 100 V. The TMUX821x devices provide consistent analog

parametric performance across the entire supply voltage range. 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, and 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.
