MUX8522 Dual 16-Channel Analog Multiplexer Module
Radiation Tolerant
GENERAL DESCRIPTION
Aeroflex’s MUX8522 is a radiation tolerant, dual 16 channel multiplexer MCM (Multi Chip Module).
The MUX8522 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 MUX8522 is ideal for
demanding military and space applications.
ORGANIZATION AND APPLICATION
The MUX8522 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 Output1(0-15).
B Section
Sixteen (16) channels addressable by bus B0~B3, enabled by EN16-31 and outputted on Output2(16-31).

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).
