This datasheet defines the design, performance, and test requirements 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 patented radiation-hardened RAD-PAK(R) technology incorporates radiation 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. 06.17.02 REV 5 All data sheets are subject to change without notice 1 (858) 503-3300 - Fax: (858) 503-3301 - www.maxwell.com (c)2021 Maxwell Technologies All rights reserved. 128 Channel Multiplexer 81840 81840 Pinout Diagram Memory 06.17.02 REV 5 All data sheets are subject to change without notice 2 (c)2021 Maxwell Technologies All rights reserved. 128 Channel Multiplexer TABLE 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 performance and affect reliability. 4. TA = 25C unless otherwise specified.
