ISL71841SEH FN8735
Rev.6.00
Nov 30, 2017 Radiation Hardened 30V 32-Channel Analog Multiplexer
The ISL71841SEH is a radiation hardened, 32-channel high
ESD protected multiplexer 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 В±10.8V to В±16.5V. It has a 5-bit address
plus an enable pin that can be driven with adjustable logic
thresholds to conveniently select one of 32 available channels.
An inactive channel is separated from an active channel by a
high impedance, which inhibits any interaction between them.
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 disables the switch to protect downstream
devices. …
