Organization and Application
The ACT8501 consists of four 16 channel muxes arranged as shown in the Block Diagram. The
ACT8501 design is inherently Radiation Hard due to the HS1840RH Multiplexers as well as
Microsemi Corp. Transient Suppressors (Reference Microsemi MicroNotes Series 050 -
page 14).
A Section
Thirty-two 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

minimizes any ESD or static buildup.
