1. General description

The IP4791CZ12 is designed to protect mobile High-Definition Multimedia

Interface (HDMI) transmitter interfaces. It includes level shifting for the Data Display

Channel (DDC), Consumer Electronic Control (CEC), hot plug signal and backdrive

protection. In addition, all signals are protected by high-level ElectroStatic

Discharge (ESD) protection diodes.

The level shifting function is required to protect the I/Os against overvoltages when the

transmitter operates at a supply voltage lower than the external devices. The IP4791CZ12

contains active buffers to provide the level shifting function, hot plug detect input and the

CEC pull-up current source.

The ESD protection diodes provide protection from ESD voltages up to ±8 kV, according

to IEC 61000-4-2, level 4.

2. Features and benefits

 HDMI 1.3 compliant

 Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen

and antimony (Dark Green compliant)

 Robust ESD protection without degradation after multiple ESD strikes

 Low leakage even after several hundred ESD discharges

 Bidirectional level shifting buffer provided for DDC clock and data channels

 Backdrive protection

 Power management

 CEC pull-up current source and level shifting buffer

 Hot plug detect module with pull-down resistor

 Matched 0.4 mm trace spacing for HDMI type C connector

3. Applications

The IP4791CZ12 can be used with a range of HDMI transmitter devices including:

 Personal computer

 Notebook

 Mobile phone

 DV camcorder

 Digital still camera

 MP3 player
