Description
The ISL71840SEH is a radiation hardened, 16-channel high ESD-protected multiplexer fabricated using the Renesas proprietary P6SOI (Silicon-on-Insulator) process technology to mitigate single-event effects and total ionizing dose. It operates with a dual supply voltage ranging from ±10.8V to ±16.5V. It has a 4-bit address plus an enable pin that can be driven with adjustable logic thresholds to conveniently select one of 16 available channels. An inactive channel is separated from an active channel by a high impedance, which inhibits any interaction between them. The ISL71840SEH's low rON allows for improved signal integrity and reduced power losses. The ISL71840SEH 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. Additionally, the ISL71840SEH incorporates input analog overvoltage protection, which disables the switch to protect downstream devices. The ISL71840SEH is available in a 28 Ld CDFP or die form and operates across the extended temperature range of -55°C to +125°C. A 32-channel version in a 48 Ld CQFP is also available.

ISL71840SEH VREF range
In the datasheet for the ISL71840SEH analog mux it says the range the VREF input is 4.5 to 5.5 V. However, if I were to use 3.3V for VREF, would it still work? On page 23 it says that about 30% of VREF is what sets the ...

What are the differences and similarities between the ISL71840SEH and the HS-1840xRH?
Question: What are the differences and similarities between the ISL71840SEH and HS-1840xRH rad hard multiplexers? Answer: Differences: Lower RON (700Ω max vs. 3000Ω max) Rail-to-Rail Input (HS-1840A/B can only do +15V to -5V) Recommended supply voltage increased to ±16.5V (HS-1840A/B ...

Do the ISL71840SEH and ISL71841SEH logic inputs support 3.3V logic?
Question: Do the logic inputs of these muxes support 3.3V logic? Answer: The logic inputs are internally compared to approximately 30% of the VREF voltage. If you apply 5.0V on VREF, this means all digital inputs are compared to 1.4V; anything higher is a logic high, and ...
