GENERAL DESCRIPTION Aeroflex’s RHD8545 is a radiation hardened, single supply, dual 16-Channel, Buffered Output, Multiplexer MCM (multi-chip module). The RHD8545 design uses specific circuit topology and layout methods to mitigate total ionization dose effects and single event latchup. These characteristics make the RHD8545 especially suited for the harsh environment encountered in Deep Space missions. It is available in a 56 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 RHD8545 is ideal for demanding military and space applications. ORGANIZATION AND APPLICATION The RHD8545 consists of two independent 16-channel buffered multiplexers arranged as shown in the block diagram. A Section Sixteen (16) channels addressable by bus A(0-3), enabled by EN(0-15) and outputted on Output1( 0-15). B Section Sixteen (16) channels addressable by bus B(0-3), enabled by EN(16-31) and outputted on Output2(16-31).
