Overview
Description
The ISL71830SEHEV1Z evaluation board is designed to provide easy access to the capabilities of the ISL71830SEH radiation tolerant, 16-channel high ESD protected multiplexers that are fabricated using Renesas' proprietary P6SOI (Silicon On Insulator) process technology to provide excellent reliability.
The evaluation board has a DIP switch, which provides a convenient way to address all channels without the need for extra supplies. There is also a BNC input available that will allow you to drive the address pins with a signal generator.
Features
- Jumper selectable input source for each input
- DIP switch to conveniently select 1 of 16 channels
- BNC input for dynamic addressing
- Multiple loading options with jumpers on VOUT
- Convenient power connection
- On-board enable switch
Applications
Applications
- Telemetry signal processing

ISL71830SEH, ISL71831SEH Radiation Tolerant 5V Multiplexers with Cold Spare
Hello, my name is Kiran Bernard, and I'm an Applications Engineer here at Intersil.
Intersil previously released the ISL71840SEH and the ISL71841SEH, which are high voltage multiplexers that were successors to our legacy HS1840A mux. The ISL71840 family followed a development process that took in customer feedback in every step to ensure that we would make a part that was competitive. Some of the feedback during that process was to make a single rail, low voltage, analog multiplexer, and that's what I'm here to talk about.
I'd like to introduce the ISL71830SEH and the ISL71831SEH. They are the 16-channel and 32-channel 5V multiplexers.
Intersil has been a leader in radiation-tolerant analog multiplexers for over 30 years, and we wanted to expand our portfolio to include lower power rails. The ISL71830 family can operate with supplies ranging from 3V to 5.5V, and just like their parent parts, they offer both low leakage and low on resistance, coupled with excellent ESD protection up to 5kV (HBM), something that pretty much all 5V radiation hardened muxes in the current market just don't have.
With a maximum input leakage of a 120nA and a maximum on resistance of a 120Ω across the whole input range with fast address transition times, the ISL71830 family provides industry leading performance.
The parts also offer cold sparing capability, so you can parallel multiple muxes on top of each other for redundant applications without sacrificing your signal integrity.
For high reliability applications, we also employed special design and layout techniques to improve its radiation tolerance. Here are some graphs that show rDS(ON) and input leakage performance for low dose rate up to 75krad, and you can see that the part is pretty much indifferent to radiation.
We've performed extensive testing on these parts, and have single event effects and total ionizing dose test reports available on the web.
