DATASHEET
Radiation Hardened 5V 32-Channel Analog Multiplexer
ISL71831SEH
The ISL71831SEH is a radiation tolerant, 32-channel
multiplexer that is fabricated using Intersil’s proprietary P6-SOI
process technology to provide excellent latch-up performance.
It operates with a single supply range from 3V to 5.5V and has
a 5-bit address line plus an enable that can be driven with
adjustable logic thresholds to conveniently select one of 32
available channels. An inactive channel is separated from the
active channel by a high impedance, which inhibits any
interaction between them.
The ISL71831SEH’s low rDS(ON) allows for improved signal
integrity and reduced power losses. The ISL71831SEH is also
designed for cold sparing making it excellent for redundancy in
high reliability applications. 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
incurring extra power dissipation. The ISL71831SEH also has
analog overvoltage protection on the input that disables the
switch during an overvoltage event to protect upstream and
downstream devices.
The ISL71831SEH is available in a 48 Ld CQFP and operates
across the extended temperature range of -55°C to +125°C.
There is also a 16-channel version available offered in a 28 Ld
CDFP, please refer to the ISL71830SEH datasheet for more
information. For a list of differences please refer to Table 1 on
page 2.
