1. The LMUX MCM is designed to operate with power supply voltages ranging  from ±5.2V to ±20VDC.
2. The maximum voltage each input AIN(128:1) may see without damage is +35V to -35V with respect to ground.
3. Stresses above the absolute maximum rating may cause permanent damage  to the device. Extended operation at   the maximum levels may degrade per-formance and affect reliability.
4. T_A  = 25°C unless otherwise specified.


Description

Maxwell Technologies' 81840 high-performance 128-channel multiplexer features a typical 300 krad (Si) total dose tolerance. This datasheet defines the design, performance, and test require- ments for a hermetic, telemetry multiplexer, multi-chip-module (MCM), utilizing chip and wire technology to be used in space systems. The 81840 is intended for use in the environments encountered by high reliability spacecraft applications. The pat- ented radiation-hardened RAD-PAK^(R) technology incorporates radi-ation shielding in the microcircuit package. Capable of surviving
in-space environment, the 81840 is ideal for satellite, spacecraft, and space probe missions. It is available up to Class K screening.
