GENERAL DESCRIPTION
Aeroflex’s MUX8561 is a radiation tolerant +5V only 16 Kelvin measurement channel multiplexer MCM
(Multi Chip Module).
The MUX8561 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
MUX8561 is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The MUX8561 consists of two 16 channel +5V only multiplexers arranged as shown in the block diagram,
addressable by bus A0~A3 including enable which connects the addressed channel to two separate 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.

3/ VEN is the applied input voltage to the enable line EN (0-15).
4/ VOUT is the applied input voltage to the output lines OUTPUT (0-15), CURRENT (0-15)
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/ The MUX8561 cannot be operated with analog inputs below 0 volts.
7/ 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, 46, 49, 50).
