ISL71840SEH

DATASHEET Radiation Hardened 30V 16-Channel Analog Multiplexer ISL71840SEH The ISL71840SEH is a radiation hardened, 16-Channel high ESD protected multiplexer that is fabricated using Intersil’s 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 1 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. The ISL71840SEH also incorporates input analog overvoltage protection, which will disable 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. There is also a 32-Channel version available called the ISL71841SEH offered in a 48 Ld CQFP, please refer to the ISL71841SEH datasheet for more information. For a list of differences please...
