13.0 AC Electrical Characteristics
(Temperature: -40°C
Data sheet specification limits are guaranteed by design, test, or statistical analysis.
Note 7: Data sheet minimum and maximum limits are guaranteed by design, test, or statistical analysis.
Note 8: The ACCESS.bus interface of the LM8333 device implements and meets the timing necessary for interface to the I
levels. The bus drivers are designed with open-drain output as required for bidirectional operation. The LM8333 device will not meet the AC timing and current/
voltage requirements of the full bus specification.
