AC ELECTRICAL CHARACTERISTICS
(V+ = 2.3V to 5.5V, GND = 0, RESET = V+, T
DC ELECTRICAL CHARACTERISTICS (continued)
(V+ = 2.3V to 5.5V, GND = 0, RESET = V+, T
(Note 1)
Note 1: All parameters are 100% production tested at T
Note 2: Minimum SCL clock frequency is limited by the MAX7310 bus timeout feature, which resets the serial bus interface if either
Note 3: A master device must internally provide a hold time of at least 300ns for the SDA signal (referred to the V
Note 4: t
Note 5: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
