ELECTRICAL CHARACTERISTICS (continued)
(V 12 = 12V, V VID = V AUD = 3.3V, V GNDVID = V EP = 0V, no load, T A = 0°C to +70°C, unless otherwise noted. Typical values are at
T A = +25°C.) (Note 1)

Note 1: All devices are 100% production tested at T
A
= +25°C. Specifications over temperature limits are guaranteed by design.
Note 2: Normal operation mode is full power with input video and load detection active.
Note 3: The settling time is measured from the 50% of the input swing to the 0.1% of the final value of the output.
Note 4: 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.
Typical Operating Characteristics
(V VID = V AUD = 3.3V, V 12 = 12V, V GNDVID = V EP = 0V, video load is 150
Ω to GNDVID, audio load is 10kΩ to EP, T
A = +25°C, unless
otherwise noted.)
