I2C 2-Wire Extender for DDC in DVI, HDMI, and VGA Interfaces

Maxim Integrated 

I2C 2-Wire Extender for DDC in DVI,

HDMI, and VGA Interfaces

ELECTRICAL CHARACTERISTICS (continued)

(VCC = +3.0V to +5.5V, VDD = +3.0V to +5.5V, TA = 0°C to +70°C. Typical values are at TA = +25°C, VCC = +5.0V, VDD = +3.3V,

unless otherwise noted.)

Note 1: While the MAX3816A is operable over the continuous range of 3.0V to 5.5V, the DDC application requires VCC connection to

DDC +5V.

Note 2: All levels in the cable side clock and data I/O are referenced to GND_REF, unless otherwise noted.

Note 3: All levels in the display side clock and data I/O are referenced to VSS, unless otherwise noted.

Note 4: Rise time measured 30% to 70%; fall time measured 70% to 30%. Load range is 60pF to 3000pF on source side, and 10pF

to 400pF on display side. Pullup resistors are chosen to supply I2C maximum of 3mA when asserting low state.
