ISL73840SEH FN8845
Rev.2.00
Dec 7, 2017 Radiation Tolerant 30V 16-Channel Analog Multiplexer
The ISL73840SEH is a radiation tolerant, 16-channel high ESD
protected multiplexer fabricated using Intersil’s proprietary
P6SOI (Silicon On Insulator) process technology. 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 ISL73840SEH’s low rON allows for improved signal
integrity and reduced power losses. The ISL73840SEH 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
ISL73840SEH also incorporates input analog overvoltage
protection, which disables the switch to protect downstream
devices. …
