GENERAL DESCRIPTION
The RHD5928 is a radiation hardened, single supply, 8 Channel Multiplexer in a 16-pin SOIC package. The
RHD5928 design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and
single event latchup. These characteristics make the RHD5928 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 RHD5928 is ideal for demanding military and space
applications.
ORGANIZATION AND APPLICATION
The RHD5928 is an 8 to 1 CMOS multiplexer. Channel selection is controlled by 3 bit binary addressing
and an active low enable. 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 1 Mrad(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 dependent.
