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.  
Failsafe logic: up to 44 V independent of supply
