May 23, 2013 Rad-Hard 16 Channel BiCMOS Analog Multiplexer with High-Z Analog Input
Protection
The HS-1840ARH, HS-1840AEH, HS-1840BRH and HS-1840BEH
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 п‚±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-1840AEH,
HS-1840BRH and HS-1840BEH 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. …
