Note 1:
All parameters are 100% production tested at T

°
C. Specifications over temperature are guaranteed by design.
Note 2:
Minimum SCL clock frequency is limited by the MAX7310 bus timeout feature, which resets the serial bus interface if either
SDA or SCL is held low for a 30ms minimum.
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 of SCL
’
s falling edge.
Note 4:

measured between 90% to 10% of V+.
Note 5:
Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
