General Description
Aeroflex's ACT8502 is a radiation hardened, multi-chip 48 channel multiplexer MCM (multi-chip module) with ESD protection for use in space applications. All channel inputs have electrostatic discharge protection. The ACT8502 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 (QFP) and is guaranteed operational from -55C to +125C. Available screened in accordance with MIL-PRF-38534, the ACT8502 is ideal for demanding military and space applications.

ACT8502 48 Channel Analog MUX Block Diagram
Organization and Application
The ACT8502 consists of six 16 channel muxes arranged as shown in the Block Diagram. The ACT8502 design is inherently Radiation Hard due to the HS1840RH Multiplexers as well as Microsemi Corp. Transient Suppressors (Reference Microsemi MicroNotes Series 050 page 14). 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. NOTE: It is recommended that all "NC or "no connect pin", be grounded. This eliminates or minimizes any ESD or static buildup.
