The ISL73841SEH is a radiation tolerant, 32-channel high ESD protected multiplexer fabricated using the proprietary Renesas P6SOI (Silicon On Insulator) process technology. It operates with a dual supply voltage ranging from ±10. 8V to ±16. 5V. It has a 5-bit address plus an enable pin that can be driven with adjustable logic thresholds to conveniently select one of 32 available channels. An inactive channel is separated from an active channel by a high impedance, which inhibits any interaction between the channels. The ISL73841SEH low rON allows for improved signal integrity and reduced power losses. The ISL73841SEH 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. The ISL73841SEH also incorporates input analog overvoltage protection, which disables the switch to protect downstream devices. The ISL73841SEH is available in a 48 Ld CQFP or die form and operates across the extended temperature range of -55°C to +125°C. A 16-channel version in a 28 Ld CDFP is also available. Refer to the ISL73840SEH datasheet for more information.
