DATASHEET

Radiation Hardened 30V 32-Channel Analog

Multiplexer

ISL71841SEH

Features

The ISL71841SEH is a radiation hardened, 32-channel high

ESD protected multiplexer that is fabricated using Intersil’s

proprietary P6SOI (Silicon On Insulator) process technology to

mitigate single event effects. It operates with a dual supply

voltage ranging from ±10.8V to ±16.5V. It has a 5-bit address

plus an enable pin that can be driven with adjustable logic

thresholds to conveniently select 1 of 32 available channels.

An inactive channel is separated from an active channel by a

high impedance, which inhibits any interaction between them.

• DLA SMD# 5962-15220

• Fabricated using P6SOI process technology

- Provides latch-up immunity

• ESD protection 8kV (HBM)

• Rail-to-rail operation

• Overvoltage protection

• Low r_ON. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <500Ω (typical)

The ISL71841SEH’s low r_ONallows for improved signal

integrity and reduced power losses. The ISL71841SEH 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

ISL71841SEH also incorporates input analog overvoltage

protection, which will disable the switch to protect downstream

devices.

• Flexible split rail operation

- Positive supply above GND (V⁺) . . . . . . . +10.8V to +16.5V

- Negative supply below GND (V^-) . . . . . . . . -10.8V to -16.5V

• Adjustable logic threshold control with VREF pin

• Cold sparing capable (from ground). . . . . . . . . . . . . . . . .±25V

• Analog overvoltage range (from ground). . . . . . . . . . . . .±35V

• Off switch leakage . . . . . . . . . . . . . . . . . . . 100nA (maximum)

• Transition times (t_R, t_F) . . . . . . . . . . . . . . . . . . . 500ns (typical)

• Break-before-make switching

The ISL71841SEH is available in a 48 Ld CQFP, 44 Ld CLCC, or

die form and operates across the extended temperature range

of -55°C to +125°C.

• Grounded metal lid (internally connected)

• Operating temperature range. . . . . . . . . . . .-55°C to +125°C

There is also a 16-channel version available offered in a 28 Ld

CDFP, please refer to the ISL71840SEH datasheet for more

information. For a list of differences please refer to Table 1 on

page 3.

• Radiation tolerance

- High dose rate (50-300rad(Si)/s). . . . . . . . . . . 100krad(Si)

- Low dose rate (0.01rad(Si)/s) . . . . 100krad(Si) (see Note)

- SEB LET_TH. . . . . . . . . . . . . . . . . . . . . . . . . 86.4MeV•cm²/mg

NOTE: Product capability established by initial characterization. All

subsequent lots are assurance tested to 50krad (0.01rad(Si)/s)

wafer-by-wafer.
