IP4776CZ38
General description
The IP4776CZ38 is designed for HDMI host-interface protection. The IP4776CZ38 includes level shifting for the DDC channels and backdrive protection for HDMI as well as high-level ESD protection diodes for the TMDS signal lines.
The level shifting function is required when the receiver operates at a supply voltage lower than the external devices to protect the I/Os against over voltages. The IP4776CZ38 contains four N-channel MOSFETs to provide this level shifting function.
Furthermore, all TMDS intra-pairs are protected by a special diode configuration offering an ultra low line capacitance of 0.7 pF only. These diodes provide protection to downstream components from ESD voltages up to +-8 kV contact according to the IEC 61000-4-2, level 4 standard.
Features
- Pb-free and RoHS compliant, Dark Green
- Integrated high-level ESD protection, level shifting and backdrive protection
- All TMDS lines with integrated rail-to-rail clamping diodes with downstream ESD protection of +-8 kV according to IEC 61000-4-2, level 4 standard
- Matched 0.5 mm trace spacing
- Bidirectional level shifting N-channel FETs provided for DDC clock and data channels
- TMDS lines with ≤ 0.05 pF matching of capacitance between the TMDS pairs
- Ultra low line capacitance of 0.7 pF per channel
- HDMI 1.3 compliant
- Backdrive protection
- 38-pin TSSOP lead-free package
