All channel inputs have electrostatic discharge protection. The ACT8503 has been specifically designed to meet exposure to radiation environments. The multiplexer is available in a 96 lead High Temperature Co-Fired Ceramic (HTCC) Quad Flatpack (QFP) and is guaranteed operational from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534, the ACT8503 is ideal for demanding military and space applications. eroflex Circuit Technology – Multiplexer Modules For The Future © SCD8503 REV A 10/26/01 Aeroflex Circuit Technology 2 SCD8503 REV A 10/26/01 Plainview NY (516) 694-6700 +VCC A0 A1 A2 A3 EN 0-15 CH 15 • • • CH 0 16 VR 16 MUX 1 -VEE EN 16-31 CH 31 16 VR 16 MUX 2 OUTPUT 16-31 GND VREF EN 32-47 CH 47 • • • CH 32 ACT8503 48 Channel Analog MUX Block Diagram OUTPUT 0-15 • • • CH 16 16 VR 16 MUX 3 OUTPUT 32-47 Organization and Application The ACT8503 consists of three 16 channel muxes arranged as shown in the Block Diagram. The Address Bus and three Enable lines providing for 48 channels addressable by Bus A0~A3, in three 16 channel blocks, each block enabled separately. Each block connects the addressed channel to one output. The ACT8503 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.
