General Description
Aeroflex’s ACT8503 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 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.

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.

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) and OUTPUT(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.
