Note 1:
All parameters are 100% production tested at T
A
= +25
°
C. Specifications over temperature are guaranteed by design.
Note 2:
Minimum SCL clock frequency is limited by the MAX7312 bus timeout feature, which resets the serial bus interface if either
SDA or SCL is held low for a minimum of 25ms. Disable bus timeout feature for DC operation.
Note 3:
A master device must internally provide a hold time of at least 300ns for the SDA signal (referred to the V
IL
of the SCL
signal) in order to bridge the undefined region SCL
’
s falling edge.
Note 4:
C
B
= total capacitance of one bus line in pF.
Note 5:
The maximum t
F
for the SDA and SCL bus lines is specified at 300ns. The maximum fall time for the SDA output stage t
F
is
specified at 250ns. This allows series protection resistors to be connected between the SDA and SCL pins and the
SDA/SCL bus lines without exceeding the maximum specified t
F
.
Note 6:
Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
