GENERAL DESCRIPTION Aeroflex’s RHD8541 is a radiation hardened, single supply, 64-Channel Multiplexer MCM (multi-chip module). The RHD8541 design uses specific circuit topology and layout methods to mitigate total ionization dose effects and single event latchup. These characteristics make the RHD8541 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 RHD8541 is ideal for demanding military and space applications. ORGANIZATION AND APPLICATION The RHD8541 consists of four, single supply, 16-Channel Multiplexers arranged as shown in the Block Diagram. The RHD8541 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) channels addressable by bus A(0-3), in two 16-channel blocks, each block enabled separately. B SECTION Thirty-two (32) channels addressable by bus B(0-3), in two 16-channel blocks, each block enabled separately.
