GENERAL DESCRIPTION Aeroflex’s RHD8542 is a radiation hardened, single supply, 48-Channel Multiplexer MCM (multi-chip module). The RHD8542 design uses specific circuit topology and layout methods to mitigate total ionization dose effects and single event latchup. These characteristics make the RHD8542 especially suited for the harsh environment encountered in Deep Space missions. It is available in a 96 lead High Temperature Co-Fired Ceramic (HTCC) Quad Flatpack (CQFP). It is guaranteed operational from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534 Class K, the RHD8542 is ideal for demanding military and space applications. ORGANIZATION AND APPLICATION The RHD8542 consists of forty-eight (48) Kelvin measurement channels addressable by bus A0~A3 in three 16 channel blocks, each block enabled separately. Each block connects the addressed channel to two outputs, "Output" and "Current". This technique enables selecting and reading a remote resistive sensor without the MUX resistance being part of the measurement. For grounded sensors, this is done by passing current to the sensor by means of the "Current" pin and reading the resultant voltage (proportional to the sensor resistance) at the "Output" pin. The device will not latch with SEU events to above 100MeV-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.
