SMBus/I 2 C Interfaced 4-Port, Level-Translating
GPIOs and LED Drivers
PORT, INTERRUPT ( INT ), AND RESET ( RST ) TIMING CHARACTERISTICS
(V DD = 1.62V to 3.6V, T A = T MIN to T MAX , unless otherwise noted. Typical values are at V DD = 3.3V, V LA = 3.3V (MAX7307 only), T A =
+25°C.) (Note 1) (See Figures 14, 15, and 16)

Note 1: All parameters are tested at T A = +25°C. Specifications over temperature are guaranteed by design.
Note 2: Guaranteed by design.
Note 3: A master device must provide a hold time of at least 300ns for the SDA signal (referred to V IL of the SCL signal) to bridge the
undefined region of SCL’s falling edge.
Note 4: C b = total capacitance of one bus line in pF. t R and t F are measured between 0.3 x V DD and 0.7 x V DD .
Note 5: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
