General Description
Aeroflex's ACT8504 is a radiation hardened, multi-chip 64 channel multiplexer MCM (multi-chip
module) with ESD protection for use in space applications. All channel inputs have electrostatic
discharge protection.
The ACT8504 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 -55C to +125C. Available screened in accordance with
MIL-PRF-38534, the ACT8504 is ideal for demanding military and space applications.

SCD8504 REV A 10/26/01 Plainview NY (516) 694-6700
Organization and Application
The ACT8504 consists of four 16 channel muxes arranged as shown in the Block Diagram.
The muxes channels 0-63 are controlled by address lines A
0
- A
3
. The mux output monitor is
controlled by address lines C
0
, C
1
.
The ACT8504 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(0-5).
2/ V
IN
is the applied input voltage to the MUXes' input channel CH0-CH63.
3/ V
EN
is the applied input voltage to the MUXes' enable line En(0-15), En(16-31), En(32-47) and En(48-63).
4/ V
OUT
is the applied input voltage to the MUXes' output line OUTPUT(1-15), OUTPUT(16-31), OUTPUT(32-47) and OUTPUT(48-63).
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.
