SCDS404A – MARCH 2021 – REVISED NOVEMBER 2021
TMUX741xF ±60 V Fault-Protected, 1:1 (SPST), 4-Channel Switches
with Latch-Up Immunity and 1.8-V Logic
1 Features
3 Description
•
Wide supply voltage range:
The TMUX7411F, TMUX7412F, and TMUX7413F
are complementary metal-oxide semiconductor
(CMOS) analog switches in 1:1 (SPST), 4-channel
configurations. The devices work well with dual
supplies (±5 V to ±22 V), a single supply (8 V to
44 V), or asymmetric supplies (such as VDD = 12 V,
VSS = –5 V). The overvoltage protection is available
in powered and powered-off conditions, making
the TMUX741xF devices suitable for applications
where power supply sequencing cannot be precisely
controlled.
– Single supply: 8 V to 44 V
– Dual supply: ±5 V to ±22 V
Integrated fault protection:
– Overvoltage protection, source to supplies or
source to drain: ±85 V
– Overvoltage protection: ±60 V
– Powered-off protection: ±60 V
– Interrupt flags to indicate fault status
– Output open circuited during fault
Latch-up immunity by device construction
6 kV human body model (HBM) ESD rating
Low On-Resistance: 8.3 Ω typical
Flat On-Resistance: 10 mΩ typical
1.8-V Logic capable

The devices block fault voltages up to +60 V or
−60 V relative to ground in powered and powered-off
conditions. When no power supplies are present the
switch channels remain in the OFF state regardless of
switch input conditions, and any control signal present
on the logic pins is ignored. If the signal path input
voltage on any Sx pin exceeds the supply voltage
(VDD or VSS) by a threshold voltage (VT), the channel
turns OFF and the Sx pin becomes high impedance.
The drain pin (Dx) of a selected channel under a fault
condition is floating. The TMUX741xF devices provide
an active-low interrupt flag (FF) to indicate if any of
the source inputs are experiencing a fault condition to
help system diagnostics.
