GENERAL DESCRIPTION Aeroflex’s RHD8540 is a radiation hardened, single supply, 64-Channel Multiplexer MCM (multi-chip module). The RHD8540 design uses specific circuit topology and layout methods to mitigate total ionization dose effects and single event latchup. These characteristics make the RHD8540 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 RHD8540 is ideal for demanding military and space applications. ORGANIZATION AND APPLICATION The RHD8540 consists of four, single supply, 16-Channel Multiplexers arranged as shown in the Block Diagram. The RHD8540 design is inherently radiation tolerant. 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. A SECTION Thirty-two (32) Kelvin measurement channels addressable by bus A0~A3, in two 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 multiplexer 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. B SECTION Thirty-two (32) channels addressable by bus B0~B3, in two 16 channel blocks, each block enabled separately. Each block connects the addressed channel to one output. By paralleling the channel inputs and enables, this section can be converted to act like one of the 16 channel blocks of the A section.
