HS-1840BEH Datasheet, PDF (1/7 Pages) Intersil Corporation – Rad-Hard 16 Channel BiCMOS Analog Multiplexer with High-Z Analog Input Protection

Rad-Hard 16 Channel BiCMOS Analog Multiplexer with
High-Z Analog Input Protection
HS-1840ARH, HS-1840AEH,
HS-1840BRH, HS-1840BEH
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.
