It is designed to provide a high input impedance to the analog source power on or off, or the analog signal voltage inadvertently exceeds the supply rails during powered operation. All channel inputs have electrostatic discharge protection. The ACT8500 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 (QFP). It is guaranteed operational from -55°C to +125°C. Available screened in accordance with the individual test methods of MIL-STD-883, the ACT8500 is ideal for demanding military and space applications. eroflex Circuit Technology – Multiplexer Modules For The Future © SCD8500 REV C 10/10/01 Aeroflex Circuit Technology 2 SCD8500 REV C 10/10/01 Plainview NY (516) 694-6700 GND VREF -VEE +VDD A0 A1 A2 A3 EN 32-47 CH 47 • • • CH 32 B0 B1 B2 B3 EN 0-15 CH 15 • • • CH 0 16 16 VR VR 16 16 16 CH 63 • • • CH 48 EN 48-63 CURRENT 32-47 OUTPUT 32-47 CH 31 EN 16-31 SECTION A OUTPUT 0-15 • • • CH 16 16 16 VR VR 16 16 16 ACT8500 64 Channel Analog MUX Block Diagram MUX 5 MUX 3 MUX 1 SECTION B MUX 6 MUX 4 MUX 2 CURRENT 48-63 OUTPUT 48-63 OUTPUT 16-31 Organization and Application The ACT8500 consists of six 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 32 channels addressable by Bus A0~A3, in two 16 channel blocks, each block enabled separately. Each block connects the addressed channel to two outputs, "Output" and "Current". This technique enables selecting and reading a remote resistive sensor without the MUX resistance being part of the measurement. For grounded sensors, this is done by passing current to the sensor by means of the "Current" pin and reading the resultant voltage (proportional to the sensor resistance) at the "Output" pin. B Section 32 channels addressable by Bus B0~B3, in two 16 channel blocks, each block enabled separately. Each block connects the addressed channel to one output. By paralleling the channel inputs and enables, this section can be converted to act like one of the 16 channel blocks of the A section. NOTE: It is recommended that all "NC or "no connect pin", be grounded. This eliminates or minimizes any ESD or static buildup.
