DATASHEET
Radiation Tolerant 5V 16-Channel Analog Multiplexer
ISL71830SEH
Features
The ISL71830SEH is a radiation tolerant, 16-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 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 them.
• DLA SMD# 5962-15247
• Fabricated using P6 SOI process technology
• Rail-to-rail operation
• No latch-up
• Low rDS(ON). . . . . . . . . . . . . . . . . . . . . . . . . .<120Ω (maximum)
• Single supply operation . . . . . . . . . . . . . . . . . . . . . . 3V to 5.5V
- Adjustable logic threshold control
The ISL71830SEH’s low rDS(ON) allows for improved 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.
