DATASHEET  
Radiation Hardened 30V 32-Channel Analog  
Multiplexer  
ISL71841SEH  
Features  
The ISL71841SEH is a radiation hardened, 32-channel high  
ESD protected multiplexer that is fabricated using Intersil’s  
proprietary P6SOI (Silicon On Insulator) process technology to  
mitigate single event effects. It operates with a dual supply  
voltage ranging from ±10.8V to ±16.5V. It has a 5-bit address  
plus an enable pin that can be driven with adjustable logic  
thresholds to conveniently select 1 of 32 available channels.  
An inactive channel is separated from an active channel by a  
high impedance, which inhibits any interaction between them.  
• DLA SMD# 5962-15220  
• Fabricated using P6SOI process technology  
- Provides latch-up immunity  
• ESD protection 8kV (HBM)  
• Rail-to-rail operation  
• Overvoltage protection  
• Low rON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <500Ω (typical)  
The ISL71841SEH’s low rON allows for improved signal  
integrity and reduced power losses. The ISL71841SEH is also  
designed for cold sparing making it excellent for high reliability  
applications that have redundancy requirements. It is  
designed to provide a high impedance to the analog source in  
a powered off condition, making it easy to add additional  
backup devices without loading signal sources. The  
ISL71841SEH also incorporates input analog overvoltage  
protection, which will disable the switch to protect downstream  
devices.  
• Flexible split rail operation  
- Positive supply above GND (V+) . . . . . . . +10.8V to +16.5V  
- Negative supply below GND (V-) . . . . . . . . -10.8V to -16.5V  
• Adjustable logic threshold control with VREF pin  
• Cold sparing capable (from ground). . . . . . . . . . . . . . . . .±25V  
• Analog overvoltage range (from ground). . . . . . . . . . . . .±35V  
• Off switch leakage . . . . . . . . . . . . . . . . . . . 100nA (maximum)  
• Transition times (tR, tF) . . . . . . . . . . . . . . . . . . . 500ns (typical)  
• Break-before-make switching  
The ISL71841SEH is available in a 48 Ld CQFP, 44 Ld CLCC, or  
die form and operates across the extended temperature range  
of -55°C to +125°C.  
• Grounded metal lid (internally connected)  
• Operating temperature range. . . . . . . . . . . .-55°C to +125°C  
There is also a 16-channel version available offered in a 28 Ld  
CDFP, please refer to the ISL71840SEH datasheet for more  
information. For a list of differences please refer to Table 1 on  
page 3.  
• Radiation tolerance  
- High dose rate (50-300rad(Si)/s). . . . . . . . . . . 100krad(Si)  
- Low dose rate (0.01rad(Si)/s) . . . . 100krad(Si) (see Note)  
- SEB LETTH . . . . . . . . . . . . . . . . . . . . . . . . . 86.4MeV•cm2/mg  
NOTE: Product capability established by initial characterization. All  
subsequent lots are assurance tested to 50krad (0.01rad(Si)/s)  
wafer-by-wafer.
