DESCRIPTION
The UTC CCVGA7C5 is an ESD solution for the VGA port
connector. This device integrates ESD protection for all signals,
Two non-inverting drivers provide buffering for the HSYNC
and VSYNC signals from the video controller IC. These buffers
accept TTL input levels and convert them to CMOS output levels
that swing between Ground and VCC These drivers have a
nominal 60output impedance to match the characteristic
impedance of the HSYNC and VSYNC lines of the video cables
typically used. The inputs of these drivers also have high
impedance pullups (50knom.) pulling up to the VAUX rail.
In addition, the DDC_CLOCK and DDC_DATA channels have
1.8kresistors pulling these inputs up to the main 5V (VCC) rail.
The upper ESD diodes for the R, G and B channels are connected to a separate supply rail (VRGB) to facilitate
interfacing to graphics controller ICs with low voltage supplies. The remaining channels are connected to the main 5
V rail (VCC). The lower diodes for the R, G and B channels are also connected to a dedicated ground pin (GNDA) to
minimize crosstalk due to common ground impedance.
ESD protection is implemented with current steering diodes designed to safely handle the high peak surge currents
associated with the IEC100042 Level4 ESD Protection Standard (±8kV contact discharge). When the channels
are subjected to an electrostatic discharge, the ESD current pulse is diverted via the protection diodes into the
positive supply rails or ground where they may be safely dissipated.
FEATURES
* 7 Channels of ESD Protection Designed to Meet
IEC100042 Level4 ESD Requirements (±8kV Contact
Discharge)
* Three Independent Supply Pins (VCC, VRGB and VAUX) to
Facilitate Operation with SubMicron Graphics Controller ICs
* Very Low Loading Capacitance from ESD Protection Diodes
at Less than 5pF Typical
* TTL to CMOS LevelTranslating Buffers for the
HSYNC and VSYNC Lines
* High impedance PullUps (50kNominal to
VAUX) for HSYNC and VSYNC Inputs
* PullUp Resistors (1.8kNominal to VCC) for
DDC_CLK and DDC_DATA Lines
