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.
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.)
