GENERAL DESCRIPTION
Aeroflex’s RHD5980 is a radiation hardened, Octal Level Shifter in a 24-pin SOIC package. The RHD5980
design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and single
event latchup. These characteristics make the RHD5980 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 RHD5980 is ideal for demanding military and
space applications.
ORGANIZATION AND APPLICATION
The RHD5980 Octal Level Shifter is a radiation hard replacement for the industry standard Bidirectional
Voltage Translators. It is capable of level shifting from the A-to-B or B-to-A input ports for nominal logic
voltages on either port of 5.0 or 3.3 volts.
The RHD5980 can level shift from 5.0V to 3.3V or 3.3V to 5.0V, and also buffer from 5.0V to 5.0V or 3.3V
to 3.3V. Ports A and B can be inputs or outputs depending on the value of DIR_AB_H.
Control inputs are the standard tri-state enable (OE_L active low) and direction control DIR_AB_H where
a HIGH logic steers data from A-to-B and active LOW steers the data from B-to-A.
The control inputs are powered from V
CCA
and accept inputs at the A bus logic levels (either 3.3V or 5.0V).
All delay parameters are less than 30nS over full -55°C to +125°C military temperature range and logic
levels. All bus and control inputs have Schmitt trigger buffers to implement low-to-high transition at
approximately 60% of the corresponding logic supply and high-to-low transition at approximately 40%
providing considerable noise immunity for slow input signals
The devices will not latch with SEU events to above 100 MeV-cm
2
/mg. Total dose degradation is minimal
to above 1Mrad(Si). Displacement damage environments to neutron fluence equivalents in the mid 10
14
neutrons per cm
2
range are readily tolerated. There is no sensitivity to low-dose rate (ELDRS) effects. SEU
effects are application dependent.
