GENERAL DESCRIPTION
Aeroflex’s ACT8511 is a radiation tolerant, 64 channel multiplexer MCM (multi-chip module) with
electrostatic discharge (ESD) protection on all channel inputs.
The ACT8511 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 ACT8511
is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The ACT8511 consists of four 16 channel multiplexers arranged as shown in the Block Diagram. The
ACT8511 design is inherently radiation tolerant.
