The ISL71030M is a radiation tolerant, 16-channel multiplexer that is fabricated using the proprietary P6 SOI process technology to provide excellent latch-up performance. It operates with a single supply range from 3V to 5. 5V and has a 4-bit address line plus an enable that can be driven with adjustable logic thresholds to conveniently select one of 16 available channels. An inactive channel is separated from the active channel by a high impedance, which inhibits any interaction between the channels. The ISL71030M low rDS(ON) allows for improved signal integrity and reduced power losses. The ISL71030M is also designed for cold sparing and is excellent for redundancy in high reliability applications. 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 incurring extra power dissipation. The ISL71030M also has analog overvoltage protection on the input that disables the switch during an overvoltage event to protect upstream and downstream devices. The ISL71030M is available in a 32 Ld TQFP and operates across the extended temperature range of -55°C to +125°C.
