GENERAL DESCRIPTION
Aeroflex’s MUX8507 is a radiation tolerant, 64 channel multiplexer MCM (multi-chip module).
The MUX8507 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 (CQFP). It is guaranteed operational
from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534, the MUX8507 is ideal for
demanding military and space applications.
ORGANIZATION AND APPLICATION
The MUX8507 consists of six 16 channel multiplexers arranged as shown in the Block Diagram. The
MUX8507 design is inherently radiation tolerant.
A SECTION
Thirty-two (32) Kelvin measurement 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 multiplexer
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
Thirty-two (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.
