Minimum and maximum values are not specified and not production tested. (2) For cases with fall time of SCL less than 20 ns and/or the rise time or fall time of SDA less than 20 ns, the hold time should be greater than 20 ns. (3) For cases with fall time of SCL less than 10 ns and/or the rise or fall time of SDA less than 10 ns, the hold time should be greater than 10 ns.
