New Radiation Hardened Multiplexers for Space Flight Data Acquisition Systems

Intersil Corp. recently launched the ISL71840SEH and ISL71841SEH, new radiation hardened (rad hard) multiplexers that offer ESD protection and high signal chain accuracy and timing performance. The ISL71840SEH 30V 16-channel multiplexer is a drop-in replacement for Intersil’s HS9-1840ARH, which has been aboard nearly every satellite and space exploration mission (e.g., NASA’s Orion flight test). For applications with form factor constraints, the ISL71841SEH offers high performance and 41% reduced board space compared with an ISL71840SEH two-chip solution.ISL71840-Intersil

Both the ISL71840SEH and ISL71841SEH offer per-switch over-voltage protection. When an input channel experiences over-voltage, the remaining channels continue sending data to the ADC. Both multiplexers provide a “cold spare” redundant capability, which enables the connection of two or three additional unpowered multiplexers to a common data bus. If needed, a redundant multiplexer is immediately activated. Both multiplexers provide a wide supply range with split-rail operation from ±10.8 V to 16.5 V and an absolute maximum of ±20 V.
