Aeroflex Plainview’s Radiation Hardness Assurance Plan is DLA Certified to MIL-PRF-38534, Appendix G.
Aeroflex’s ACT8506 is a radiation tolerant, 48 channel multiplexer MCM (multi-chip module).
The ACT8506 has been specifically designed to meet exposure to radiation environments. The multiplexer
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, the
ACT8506 is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The ACT8506 consists of six 16 channel multiplexers arranged as shown in the Block Diagram. The
ACT8506 design is inherently radiation tolerant.
The ACT8506 consists of forty-eight (48) 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.
