The ACT8505 consists of four 16 channel muxes arranged as shown in the Block Diagram. The muxes channels 0-63 are controlled by address lines - A3. The mux output monitor is controlled by address lines C0, C1. The ACT8505 design is inherently Radiation Hard due to the HS1840RH Multiplexers as well as Microsemi Corp. Transient Suppressors (Reference Microsemi MicroNotes Series 050 page 14).
NOTE: It is recommended that all "NC or "no connect pin", be grounded. This eliminates or minimizes any ESD or static buildup.
