TMUX8212
SCDS434A – OCTOBER 2021 – REVISED DECEMBER 2021
TMUX821x 100-V, Flat Ron, 1:1 (SPST), 4-Channel Switches
with Latch-Up Immunity and 1.8-V Logic
1 Features
3 Description
•
High supply voltage capable:
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.
– Dual supply: ±10 V to ±50 V
– Single supply: 10 V to 100 V
– Asymmetric dual supply operation
Consistent parametrics across supply voltages
Latch-up immune
High continuous current: 200 mA
Low crosstalk: –110 dB
Low input leakage: 10 pA
Low on-resistance flatness: 0.05 Ω
Low on-resistance: 5 Ω
Low capacitance: 12 pF
Removes need for additional logic rail (VL)
1.8-V Logic capable
Fail-safe logic: up to 48 V independent of supply
Integrated pull-down resistor on logic 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.
Wide operating temperature TA: –40°C to 125°C
Industry-standard TSSOP and
smaller WQFN packages
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.
