Digital I/O, RF/Microwave, Matrix, and Multiplexer Plug-Ins
Digital I/O (e.g., 1260-114), RF/microwave (e.g. 1260-150), matrix
(e.g., 1260-145), and multiplexer (e.g. 1260-138A) plug-ins require
no de-rating. As always, the current through any connector pin
must not exceed the rated channel current. For example, if current
passes simultaneously through two inputs of the same multiplexer,
the common side carries the current from both. The common
current must not exceed the rated channel current.
