説明
The ISL71840SEH is a radiation hardened, 16-channel high ESD-protected multiplexer fabricated using the Renesas 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 one 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. Additionally, the ISL71840SEH incorporates input analog overvoltage protection, which disables 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. A 32-channel version in a 48 Ld CQFP is also available.
