DATASHEET

Radiation Hardened 30V 16-Channel Analog

Multiplexer

ISL71840SEH

Features

The ISL71840SEH is a radiation hardened, 16-channel high

ESD protected multiplexer that is fabricated using Intersil’s

proprietary P6SOI (Silicon On Insulator) process technology to

mitigate single-event effects and total ionizing dose. 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 1

of 16 available channels. An inactive channel is separated

from an active channel by a high impedance, which inhibits

any interaction between them.

• DLA SMD# 5962-15219

• Fabricated using P6SOI process technology

- Provides latch-up immunity

• ESD protection 8kV (HBM)

• Rail-to-rail operation

• Overvoltage protection

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

• Flexible split rail operation

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

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

The ISL71840SEH’s low r_ONallows for improved signal

integrity and reduced power losses. The ISL71840SEH 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

ISL71840SEH also incorporates input analog overvoltage

protection, which will disable the switch to protect downstream

devices.

• 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 ISL71840SEH is available in a 28 Ld CDFP 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

• Radiation tolerance

There is also a 32-channel version available offered in a 48 Ld

CQFP, please refer to the ISL71841SEH datasheet for more

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

page 3.

- 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.
