Description
The ISL71830SEH is a radiation tolerant, 16-channel multiplexer that is fabricated using the proprietary P6-SOI (Silicon-on-Insulator) 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. 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. The ISL71830SEH is available in a 28 Ld CDFP and operates across the extended temperature range of -55°C to +125°C. A 32-channel version is also available, offered in a 48 Ld CQFP. Refer to the ISL71831SEH datasheet for more information.

What is the maximum switching frequency the ISL71830SEH and ISL71831SEH can support?
Question: What is the maximum switching frequency these rad hard muxes can support? Answer: This is usually limited by the address propagation delays, as you want to keep the transition less than 10% of the pulse width.The max frequency would be 1 MHz.
-
Do the ISL71830SEH and ISL71831SEH rad hard multiplexers have cold spare capability?
Question: Do these rad hard muxes have cold spare capability? Answer: Yes, they do. The inputs of the ISL7183XSEH are designed to provide a high-Z input impedance when powered off so that redundant multiplexers do not load the inputs of the primary multiplexer.
