The HS-1840ARH, HS-1840AEH, HS-1840BRH and HS-1840BEH
Features
are radiation hardened, monolithic 16 channel multiplexers
• Electrically screened to SMD # 5962-95630
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 severalmultiplexers 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.
• QML qualified per MIL-PRF-38535 requirements
• Pin-to-pin for Intersil’s HS-1840RH and HS-1840/883S
• Improved radiation performance
5
- Gamma dose () 3x10 RAD(Si)
• Improved r
DS(ON)
Linearity
• Improved access time 1.5µs (Max) over temp and post rad
• High analog input impedance 500Mduring power loss (open)
• 35V input overvoltage protection (power on or off)
• Dielectrically isolated device islands
• Excellent in Hi-Rel redundant systems
• Break-before-make switching
• No latch-up
