GENERAL DESCRIPTION
Aeroflex’s MUX8522 is a radiation tolerant, dual 16 channel multiplexer MCM (Multi Chip Module).
The MUX8522 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 MUX8522 is ideal for
demanding military and space applications.
ORGANIZATION AND APPLICATION
The MUX8522 consists of two independent 16 channel multiplexers arranged as shown in the block
diagram.
A Section
Sixteen (16) channels addressable by bus A
