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 clamp during the sync pulse.
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.
APPLICATIONS
• Standard and high definition television sets
• Peri-television sets.
