GENERAL DESCRIPTION
Aeroflex’s RHD5922 is a radiation hardened, single supply, 16 channel sample-and-hold multiplexer in a
24-pin SOIC package. The RHD5922 design uses specific circuit topology and layout methods to mitigate
total ionizing dose effects and single event latchup. These characteristics make the RHD5922 especially
suited for the harsh environment encountered in Deep Space missions. It is guaranteed operational from
-55°C to +125°C. Available screened in accordance with MIL-PRF-38534 Class K, the RHD5922 is ideal
for demanding military and space applications.
ORGANIZATION AND APPLICATION
The RHD5922 is a 16 to 1 CMOS sample-and-hold multiplexer. Channel selection is controlled by a 4 bit
address bus. Signal aquisition is controlled by the sample-and-hold. Low internal leakage allows for droop
rate as low as 0.1V/sec
All inputs and outputs are diode protected.
The devices will not latch with SEU events to above 100 MeV-cm2/mg. Total dose degradation is
minimal to above 1Mrad(Si). Displacement damage environments to neutron fluence equivalents
in the mid 1014 neutrons per cm2 range are readily tolerated. There is no sensitivity to low-dose
rate (ELDRS) effects. SEU effects are application dependant.
