Description

The TDA867540B is an electronic component model that falls under the product category of IC Chips. It is designed for switching between two RGB or YUV video sources and allows for parallel connection of multiple devices by setting the outputs to a high-impedance state. The device has a SEL pin (pin 5) that can be set to a HIGH level to select the video inputs of Channel 2. The IOCNTR control pin (pin 16) determines the 3-state outputs and clamp inputs, with options for 3-state outputs, passive clamp at the video inputs with diodes, or active clamp with an active clamp during the sync pulse.

Specifications and features

• YUV/RGB and fast blanking switch
• 3-state output
• Selectable clamp:
  • Passive (with diodes)
  • Active clamp
• Bandwidth greater than 22 MHz
• Fully ESD protected
• Latch-up free

Application Scenarios

The TDA867540B is commonly used in standard and high definition television sets, as well as peri-television sets.

Comparison
