GENERAL DESCRIPTION
Aeroflex’s ACT8508 is a radiation tolerant, 32 channel multiplexer MCM (multi-chip module) with
electrostatic discharge (ESD) protection on all channel inputs.
The ACT8508 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 (CQFP). It is guaranteed
operational from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534, the ACT8508
is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The ACT8508 consists of two 16 channel multiplexers arranged as shown in the Block Diagram. The
ACT8508 design is inherently radiation tolerant.
A SECTION
Sixteen (16) channels addressable by bus A0~A3, in one 16 channel block including enable.
B SECTION
Sixteen (16) channels addressable by bus B0~B3, in one 16 channel block including enable.

Notes:
1/ Measure inputs sequentially. Ground all unused inputs of the device under test. VA is the applied input voltage to the address lines A(0-3). VB
is the applied input voltage to the address lines B(0-3).
2/ VIN is the applied input voltage to the input channels CH0-CH31.
3/ VEN is the applied input voltage to the enable lines En(0-15), En(16-31).
4/ VOUT is the applied input voltage to the output lines OUTPUT(0-15), OUTPUT(16-31).
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/ Not tested, guaranteed to the specified limits.
7/ These parameters for Tc = -55°C are guaranteed by design, characterization, or correlation to other test parameters but not production tested.
