ISL73840SEH
Radiation Tolerant 30V 16-Channel Analog Multiplexer
DATASHEET
The ISL73840SEH is a radiation tolerant, 16-channel high ESD protected multiplexer fabricated using the Renesas proprietary P6SOI (Silicon On Insulator) process technology. 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 ISL73840SEH’s low rON allows for improved signal integrity and reduced power losses. The ISL73840SEH 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 ISL73840SEH also incorporates input analog overvoltage protection, which disables the switch to protect downstream devices.
The ISL73840SEH 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. Refer to the ISL73841SEH datasheet for more information. For a list of differences between the ISL73840SEH and ISL73841SEH, refer to Table 1 on page 3.
