NI 6581/6581B Specifications
100 MHz Single-Ended High-Speed Digital I/O Adapter Module
This document lists specifications for the NI 6581/NI 6581B adapter module. Pair these
specifications with the specifications listed in your NI FlexRIO FPGA specifications
document. For more information about safety and electromagnetic compatibility, refer to the
Read Me First: Safety and Electromagnetic Compatibility document included in your
hardware kit or available at ni.com/manuals.
Caution To avoid permanent damage to the NI 6581/NI 6581B, disconnect all
signals connected to the NI 6581/NI 6581B before powering down the module, and
only connect signals after the module has been powered on by the
NI FlexRIO FPGA module.
Note All numeric specifications are typical unless otherwise noted. All graphs
illustrate the performance of a representative module.
The NI 6581B is compatible with all NI FlexRIO FPGA modules. The NI 6581 variant is
compatible with the NI PXI-795xR and NI PXIe-796xR FPGA modules only.
Specifications are subject to change without notice. For the most recent device specifications,
