A 30 x 5 Microelectronic Commutator

A 30 x 5 microelectronic commutator was designed and constructed for multiplexing sensor signals into an IRIG telemetry format. Logic control and selection are provided by 23 Texas Instruments solid circuits, signal transmission is via diode gates, and power conversion is internal. Dissipation is 1 watt, weight less than 6 ounces, and dimensions are 3 x 2 x 0.9 cubic inches. A complete series of tests was completed for application to the launch and orbit environments of space vehicles.
