Rad-Hard 16 Channel CMOS Analog Multiplexer

with High-Z Analog Input Protection

HS-1840ARH, HS-1840BRH

The HS-1840ARH, HS-1840BRH are radiation hardened,

monolithic 16 channel multiplexers constructed with the

Intersil Rad-Hard Silicon Gate, bonded wafer, Dielectric

Isolation process. They are designed to provide a high input

impedance to the analog source if device power fails

(open), or the analog signal voltage inadvertently exceeds

the supply by up to ±35V, regardless of whether the device

is powered on or off. Excellent for use in redundant

applications, since the secondary device can be operated in

a standby unpowered mode affording no additional power

drain. More significantly, a very high impedance exists

between the active and inactive devices preventing any

interaction. One of sixteen channel selections is controlled

by a 4-bit binary address plus an Enable-Inhibit input which

conveniently controls the ON/OFF operation of several

multiplexers in a system. All inputs have electrostatic

discharge protection. The HS-1840ARH, HS-1840BRH are

processed and screened in full compliance with

MIL-PRF-38535 and QML standards. The devices are

available in a 28 Ld SBDIP and a 28 Ld Ceramic Flatpack.

Specifications for Rad Hard QML devices are

controlled by the Defense Supply Center in

Columbus (DSCC). The SMD numbers listed here

must be used when ordering.

Detailed Electrical Specifications for these devices

are contained in SMD 5962-95630. A “hot-link” is

provided on our homepage for downloading.
