GENERAL DESCRIPTION
Aeroflex’s ACT8501 is a radiation tolerant, 64 channel multiplexer MCM (multi-chip module) with
electrostatic discharge (ESD) protection on all channel inputs.
The ACT8501 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 ACT8501
is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The ACT8501 consists of four 16 channel multiplexers arranged as shown in the Block Diagram. The
ACT8501 design is inherently radiation tolerant.
A SECTION
Thirty-two (32) channels addressable by bus A0~A3, in two 16 channel blocks, each block enabled
separately.
B SECTION
Thirty-two (32) channels addressable by bus B0~B3, in two 16 channel blocks, each block enabled
separately.
