Radiation Tolerant 30V 32-Channel Analog Multiplexer
ISL73841SEH
The ISL73841SEH is a radiation tolerant, 32-channel high ESD
protected multiplexer that is fabricated using Intersil’s
proprietary P6SOI (Silicon On Insulator) process technology. 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.
The ISL73841SEH low rON allows for improved signal integrity
and reduced power losses. The ISL73841SEH 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
ISL73841SEH also incorporates input analog overvoltage
protection, which will disable the switch to protect downstream
devices.
The ISL73841SEH is available in a 48 Ld CQFP or die form 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 ISL73840SEH datasheet for more
information. For a list of differences please refer to Table 1 on
page 3.
