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 VCCA 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-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 dependent.
