DATASHEET ISL71831SEH FN8759 Rev 4.00 Radiation Hardened 5V 32-Channel Analog Multiplexer Mar 14, 2018 The ISL71831SEH is a radiation tolerant, 32-channel Features multiplexer that is fabricated using the Renesas proprietary DLA SMD 5962-15248 P6-SOI process technology to provide excellent latch-up performance. It operates with a single supply range from 3V to Fabricated using P6 SOI process technology 5.5V and has a 5-bit address line plus an enable that can be Rail-to-rail operation driven with adjustable logic thresholds to conveniently select No latch-up one of 32 available channels. An inactive channel is separated from the active channel by a high impedance, which inhibits Low r <120 (maximum) DS(ON) any interaction between them. Single supply operation 3V to 5.5V The ISL71831SEHs low r allows for improved signal DS(ON) Adjustable logic threshold control integrity and reduced power losses. The ISL71831SEH is also Cold sparing capable -0.4V to 7V designed for cold sparing, making it excellent for redundancy in high reliability applications. It is designed to provide a high Analog overvoltage range -0.4V to 7V impedance to the analog source in a powered off condition, Switch input off leakage . 120nA making it easy to add additional backup devices without Transition times (t ) 70ns AHL incurring extra power dissipation. The ISL71831SEH also has analog overvoltage protection on the input that disables the Internally grounded metal lid switch during an overvoltage event to protect upstream and Break-before-make switching downstream devices. ESD protection 5kV (HBM) The ISL71831SEH is available in a 48 Ld CQFP and operates Operating temperature range -55C to +125C across the extended temperature range of -55C to +125C. Radiation tolerance There is also a 16-channel version available offered in a 28 Ld - Low dose rate (0.01rad(Si)/s) .75krad(Si) CDFP. Refer to the ISL71830SEH datasheet for more + 2 - SEL/SEB LET (V = 6.3V) . 60MeVcm /mg information. For a list of differences, refer to Table 1 on TH page 2. NOTE: All lots are assurance tested to 75krad (0.01rad(Si)/s) wafer-by-wafer.

These Pb-free Hermetic packaged products employ 100% Au plate - e4 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations. 2. Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed must be used when ordering. 3. The /PROTO and /SAMPLE are not rated or certified for Total Ionizing Dose (TID) or Single Event Effect (SEE) immunity. These parts are intended for engineering evaluation purposes only. The /PROTO parts meet the electrical limits and conditions across the temperature range specified in the DLA SMD and are in the same form and fit as the qualified device. The /SAMPLE die is capable of meeting the electrical limits and conditions specified in the DLA SMD at +25C only. The /SAMPLE is a die and does not receive 100% screening across the temperature range to the DLA SMD electrical limits. These part types do not come with a certificate of conformance because there is no radiation assurance testing and they are not DLA qualified devices. 4. Evaluation board uses the /PROTO parts. The /PROTO parts are not rated or certified for Total Ionizing Dose (TID) or Single Event Effect (SEE) immunity. TABLE 1.
