Description
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 ±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. Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-95630.
