GENERAL DESCRIPTION
Aeroflex’s ACT8508 is a radiation tolerant, 32 channel multiplexer MCM (multi-chip module) with
electrostatic discharge (ESD) protection on all channel inputs.
The ACT8508 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 ACT8508
is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The ACT8508 consists of two 16 channel multiplexers arranged as shown in the Block Diagram. The
ACT8508 design is inherently radiation tolerant.
A SECTION
Sixteen (16) channels addressable by bus A0~A3, in one 16 channel block including enable.
B SECTION
Sixteen (16) channels addressable by bus B0~B3, in one 16 channel block including enable.
