General Description
Aeroflex's ACT8500 is a radiation hardened, multi-chip 64 channel multiplexer MCM (multi-chip module) with ESD protection for use in space applications. It is designed to provide a high input impedance to the analog source power on or off, or the analog signal voltage inadvertently exceeds the supply rails during powered operation. All channel inputs have electrostatic discharge protection. The ACT8500 has been specifically designed to meet exposure to radiation environments. It is available in a 96 lead High Temperature Co-Fired Ceramic (HTCC) Quad Flatpack (QFP). It is guaranteed operational from -55C to +125C. Available screened in accordance with the individual test methods of MIL-STD-883, the ACT8500 is ideal for demanding military and space applications.

ACT8500 64 Channel Analog MUX Block Diagram
Organization and Application
The ACT8500 consists of six 16 channel muxes arranged as shown in the Block Diagram. The ACT8501 design is inherently Radiation Hard due to the HS1840RH Multiplexers as well as Microsemi Corp. Transient Suppressors (Reference Microsemi MicroNotes Series 050 - page 14). A Section 32 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 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. B Section 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.
NOTE: It is recommended that all "NC or "no connect pin", be grounded. This eliminates or minimizes any ESD or static buildup.
