ISL71830SEH
Radiation Tolerant 5V 16-Channel Analog Multiplexer
The ISL71830SEH is a radiation tolerant, 16-channel
multiplexer that is fabricated using the 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 4-bit address line plus an
enable that can be driven with adjustable logic
thresholds to conveniently select one of 16 available
channels. An inactive channel is separated from the
active channel by a high impedance, which inhibits
any interaction between the channels.
Features
▪ DLA SMD# 5962-15247
▪ Fabricated using P6 SOI process technology
▪ Rail-to-rail operation
▪ No latch-up
▪ Low r
: <120Ω (maximum)
DS(ON)
▪ Single supply operation: 3V to 5.5V
• Adjustable logic threshold control
▪ Cold sparing capable: -0.4V to 7V
▪ Analog overvoltage range: -0.4V to 7V
▪ Switch input off leakage: 120nA
The ISL71830SEH low r
allows for improved
DS(ON)
signal integrity and reduced power losses. The
ISL71830SEH 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
ISL71830SEH also has analog overvoltage protection
on the input that disables the switch during an
overvoltage event to protect upstream and
downstream devices.
▪ Transition times (t
): 70ns
