ISL71841SEHVX

The ISL71841SEH is a radiation hardened, 32-channel high ESD protected multiplexer fabricated using the Renesas proprietary P6SOI (Silicon On Insulator) process technology to mitigate single event effects. 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 them. The ISL71841SEH’s low r_ON allows for improved signal integrity and reduced power losses. The ISL71841SEH 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 ISL71841SEH also incorporates input analog overvoltage protection, which disables the switch to protect downstream devices. The ISL71841SEH is available in a 48 Ld CQFP, 44 Ld CLCC, 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.
