RGB/YUV and fast blanking switch TDA8601
FEATURES
• YUV/RGB and fast blanking switch
• 3-state output
• Selectable clamp:
– passive (with diodes) or
– active clamp
• Bandwidth greater than 22 MHz
• Fully ESD protected
• Latch-up free.
GENERAL DESCRIPTION
The device is intended for switching between two RGB or
YUV video sources. The outputs can be set to a
high-impedance state to enable parallel connection of
several devices.
A HIGH level on SEL (pin 5) selects the video inputs of
Channel 2. The IOCNTR control pin (pin 16) defines the
3-state outputs and clamp inputs:
• HIGH = 3-state outputs (also for test; active clamp)
• LOW = passive clamp at the video inputs (diode)
• Sandcastle: the video signal is clamped with an active
APPLICATIONS
clamp during the sync pulse.
• Standard and high definition television sets
• Peri-television sets.

HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices.
ESD in accordance with
“MIL STD 883C” -“Method 3015”
:
1. Human body model: 1500 Ω, 100 pF, 3 pulses positive and 3 pulses negative on each pin with respect to ground.
Class 2: 2000 to 3999 V.
2. Machine model: 0 Ω, 200 pF, 3 pulses positive and 3 pulses negative on each pin with respect to ground. The IC
withstands 200 V.
