It asserts the new state with a Prevents Ringing Due to Reflections by rail-to-rail slew-rate-limited driver capable of meeting Terminating Transmission Line Impedance After 2 I C rise- and fall-time requirements under the full load Transitions of the cable. After assertion of the new state, a holdoff Use with MAX3815 TMDS Equalizer to Form a period of 2.5s prevents a subsequent state change Complete Digital Video Extension Solution while the cable channel settles. 3.0V to 5.5V Power Supply Under full load at 100kbps, the MAX3816A consumes Optional Voltage Translation Between 5V Cable 25mW, excluding pullup resistors. It is available in a DDC and 3.3V Display DDC Levels 16-pin TSSOP package and operates from 0C to +70C.
