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.
A Section
Sixteen (16) channels addressable by bus A₀~A₃, enabled by EN0-15 and outputted on Output 1( 0-15).
B Section
Sixteen (16) channels addressable by bus B₀~B₃, enabled by EN16-31 and outputted on Output 2(16-31).
