GENERAL DESCRIPTION
Aeroflex’s MUX8523 is a radiation tolerant, dual 16 channel multiplexer MCM (Multi Chip Module) with
electrostatic discharge (ESD) protection on all channel inputs.
The MUX8523 has been specifically designed to meet exposure to radiation environments. It is available
in a 56 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
MUX8523 is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The MUX8523 consists of two independent 16 channel multiplexers arranged as shown in the block
diagram.

Notes:
1/ All measurements are made with respect to ground.
NOTICE: Stresses above those listed under "Absolute Maximums Rating" may cause permanent damage to the device. These are stress rating
only; functional operation beyond the "Operation Conditions" is not recommended and extended exposure beyond the "Operation Conditions" may
affect device reliability.
