Data Sheet Conventions
OVERBAR
Indicates 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
Logic State

Note:
Values for VIL, VOL, VIH, and VOH are defined by individual product specifications.
