Technical content

Aeroflex’s ACT8512 is a radia tion tolerant, 48 channel multiple xer MCM (multi-chip module) with electrostatic discharge (ESD) protection on all channel inputs. The ACT8512 has been specifically designed to meet exposure to radiation environments. The multiplexer is available in a 96 lead High Temperature Co-F ired Ceramic (HTCC) Quad Flatpack (CQFP). It is guaranteed operational from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534, the ACT8512 is ideal for demanding military and space applications. ORGANIZATION AND APPLICATION The ACT8512 consists of six 16 channel multiplexers arranged as shown in the Block Diagram. The ACT8512 design is inherently radiation tolerant. The ACT8512 consists of forty-eight (48) channels addressable by bus A 0~A3 in three 16 channel blocks, each block enabled separately. Each block connects th e addressed channel to two outputs, "Output" and "Current". This technique enable s 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.
