Rev 4.00
Nov 30, 2017 Radiation Hardened 30V 16-Channel Analog Multiplexer
The ISL71840SEH is a radiation hardened, 16-channel high
ESD protected multiplexer fabricated using Intersil’s
proprietary P6SOI (Silicon On Insulator) process technology to
mitigate single-event effects and total ionizing dose. It
operates with a dual supply voltage ranging from В±10.8V to
В±16.5V. It has a 4-bit address plus an enable pin that can be
driven with adjustable logic thresholds to conveniently select
one of 16 available channels. An inactive channel is separated
from an active channel by a high impedance, which inhibits
any interaction between them.
The ISL71840SEH’s low rON allows for improved signal
integrity and reduced power losses. The ISL71840SEH 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
ISL71840SEH also incorporates input analog overvoltage
protection, which disables the switch to protect downstream …
