Aeroflex Plainview’s Radiation Hardness Assurance Plan is DLA Certified to MIL-PRF-38534, Appendix G.
GENERAL DESCRIPTION
Aeroflex’s RHD5964 is a radiation hardened, single supply, Voltage Reference in a 3-pad SMD-0.5
Packages. The RHD5964 design uses specific circuit topology and layout methods to mitigate total ionizing
dose effects and single event latchup. These characteristics make the RHD5964 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 RHD5964 is ideal for
demanding military and space applications.
The RHD5964 integrated circuit die is mounted directly to the metal signal pad providing optimum thermal
conduction to the printed circuit board bond sites.

Notes:
1/ Specification derated to reflect Total Dose exposure to 1 Mrad(Si) @ +25°C.
2/ Not tested. Shall be guaranteed by design, characterization, or correlation to other test parameters.
3/ Reference temperature coefficient is defined as the absolute value of the difference from the maximum and minimum voltage over the specified
temperature range, divided by the change in temperature and converted into ppm/°C.
4/ Reference change with temperature is defined as the absolute value of the difference from the maximum and minimum voltage over the specified
temperature range represented as a percentage.
5/ Not tested. Shall be guaranteed to specified limits after 1000hr life test
