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. 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 ACT8502 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) or as a
Plastic Encapsulated Chip-on-board (COB) Flatpack. It is guaranteed operational from -55°C to
+125°C. Available screened in accordance with MIL-PRF-38534, the ACT8502 is ideal for
demanding military and space applications.

Organization and Application
The ACT8502 consists of six 16 channel muxes arranged as shown in the Block Diagram. The
Address Bus and three Enable lines providing the following organization and capability.
48 channels addressable by Bus A ~A , in Three 16 channel blocks, each block enabled
0
3
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.
