Data Sheet Conventions

OVERBAR

Used to indicate a signal that is active when pulled low (For example, the RESET pin is active when

low.)

“asserted”

Means that a high true (active high) signal is high or that a low true (active low) signal is low

“deasserted” Means that a high true (active high) signal is low or that a low true (active low) signal is high

Examples:

Signal/Symbol
