Logic Families

Logic families are groups of logic circuits with standardized voltage levels that constitute a valid logic state. All circuits within a logic family are compatible with other circuits within that family, because they share the same characteristics.

Logic families can be defined by single-ended voltage levels, such as the 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, or 5.0 V logic families, or by differential voltage levels, such as low-voltage emitter-coupled logic (LVPECL) and low-voltage differential signaling (LVDS).

Refer to Configuring Voltage Levels for more information about using NI-HSDIO to select logic families and configure your voltage levels.

Note  If you use the NI 655x devices, you can configure custom voltage levels for your operation.
