DATASHEET

ISL73841SEH

Radiation Tolerant 30V 32-Channel Analog Multiplexer

The ISL73841SEH is a radiation tolerant, 32-channel high ESD

protected multiplexer fabricated using the proprietary Renesas

P6SOI (Silicon On Insulator) process technology. 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 one of 32

available channels. An inactive channel is separated from an

active channel by a high impedance, which inhibits any

interaction between the channels.

Features

• DLA SMD #5962-15220

• Fabricated using P6SOI process technology

• ESD protection 8kV (HBM)

• Rail-to-rail operation

• Overvoltage protection

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

The ISL73841SEH low r_ONallows for improved signal integrity

and reduced power losses. The ISL73841SEH 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

ISL73841SEH also incorporates input analog overvoltage

protection, which disables 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 ISL73841SEH is available in a 48 Ld CQFP 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

A 16-channel version in a 28 Ld CDFP is also available. Refer

to the ISL73840SEH datasheet for more information. For a list

of differences between the ISL73841SEH and ISL73840SEH,

refer to Table 1 on page 3.

• Radiation tolerance

- Low dose rate (0.01rad(Si)/s) . . . . . . . 50krad(Si) (Note 1)

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

NOTE:

1. Product capability established by initial characterization. All

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

wafer-by-wafer.
