Radiation Hardened 5V, 32-Channel, High ESD Protected Multiplexer Evaluation Board
The ISL71831SEHEV1Z evaluation board is designed to provide easy access to the capabilities of the ISL71831SEH radiation tolerant, 32-channel high ESD protected...
概要
説明
The ISL71831SEH is a radiation tolerant, 32-channel multiplexer that is fabricated using the Renesas 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. Refer to the ISL71830SEH datasheet for more information.

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. For more information, or to order flight parts, prototypes or evaluation boards for the ISL71830SEH, and ISL71831SEH, please visit the ISL71830SEH product page. Thank you.
