Note 1: All devices are 100% production tested at TA = +25NC. Temperature limits are guaranteed by design.

Note 2: Green 538nm LED chosen for production is such that the IC responds to 100 lux fluorescent light with 100 lux.

Note 3: With respect to green LED 538nm response.

Note 4: A master device must provide a hold time of at least 300ns for the SDA signal (referred to VIL of the SCL signal) to bridge

the undefined region of SCL’s falling edge.
