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
2
C bus and SMBus protocol at logic
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.
