GENERAL DESCRIPTION
Aeroflex’s MUX8523 is a radiation tolerant, dual 16 channel multiplexer MCM (Multi Chip Module) with
electrostatic discharge (ESD) protection on all channel inputs.
The MUX8523 has been specifically designed to meet exposure to radiation environments. It is available
in a 56 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
MUX8523 is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The MUX8523 consists of two independent 16 channel multiplexers arranged as shown in the block
diagram.
A Section
Sixteen (16) channels addressable by bus A0~A3, enabled by EN0-15 and outputted on Output 1( 0-15).
B Section
Sixteen (16) channels addressable by bus B0~B3, enabled by EN16-31 and outputted on Output 2( 16-31).

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 line EN (0-15) and EN (16-31).
4/ VOUT is the applied input voltage to the output lines OUTPUT1 (0-15), OUTPUT2 (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.

Notes:
1. It is recommended that all "NC" or "no connect pin", be grounded. This eliminates or minimizes any ESD or static buildup.
2. Package lid is internally connected to circuit ground (Pins 7, 8, 11, 21, 22, 35, 36, 49, 50).
