General Description
Aeroflex’s ACT8502 is a radiation hardened, multi-chip 48 channel multiplexer MCM (multi-chip
module) with ESD protection for use in space applications. All channel inputs have electrostatic
discharge protection.
The ACT8502 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 ACT8502 is ideal for demanding military and space applications.

Organization and Application
The ACT8502 consists of six 16 channel muxes arranged as shown in the Block Diagram. The
ACT8502 design is inherently Radiation Hard due to the HS1840RH Multiplexers as well as
Microsemi Corp. Transient Suppressors (Reference Microsemi MicroNotes Series 050 -
page 14).
48 channels addressable by Bus A ~A , in Three 16 channel blocks, each block enabled
0
3
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.
NOTE: It is recommended that all "NC or "no connect pin", be grounded. This eliminates or
minimizes any ESD or static buildup.

Notes:
1/ Measure inputs sequentially. Ground all unused inputs of the MUX under test. VA is the applied input voltage to the MUXes’ address lines A(0-3).
2/ VIN is the applied input voltage to the MUXes’ input channel CH0-CH47.
3/ VEN is the applied input voltage to the MUXes’ enable line En(0-15), En(16-31) and En(32-47).
4/ VOUT is the applied input voltage to the MUXes’ output line OUTPUT(0-15), OUTPUT(16-31), OUTPUT(32-47), CURRENT(0-15) ,
CURRENT(16-31) and CURRENT(32-47).
5/ Negative current is the current flowing out of each of the MUX pins. Positive current is the current flowing into each MUX pin.
6/ If not tested, shall be guaranteed to the specified limits.
