VGA interface with integrated h-sync buffer, ESD protection and termination resistor
The IP4774CZ14 is a VGA or DVI-I interface intended for connection between a video transmitter such as a PC graphics card and a VGA or DVI-I receiver, such as a PC monitor. The IP4774CZ14 has ESD protection for the DDC lines, ESD protection plus buffering for the h-sync line, and high-level ESD protection diodes for the RGB video signal lines.
The h-sync signal is buffered by a non-inverting buffer which can accept TTL-level input. The buffer convert TTL-level input to CMOS-level output which swings between VCC(SYNC) and GND.
An external termination resistor can be added to achieve the desired termination, which is typically required for the h-sync line of the video interface.
The IP4774CZ14 has a typical output resistance (RO) of 10 Ω
Features and benefits
- Integrated high-level ESD protection, buffering, sync-signal impedance matching
- All pin connections have integrated rail-to-rail clamping diodes providing downstream ESD protection of +-8 kV according to IEC 61000-4-2, level 4
- Driver for h-sync line
- Line capacitance < 4 pF per channel
Applications
Buffer and terminating channels, reduce EMI/RFI and provide downstream ESD protection for:
- VGA interfaces including DDC channels
- Desktop and notebook PCs, LCD TVs and PC monitors
- Graphics cards
- Set-top boxes
- Game consoles
- DVD players

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
