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.
