Functional Features

  • Bidirectional signal switching between two devices
  • Low power consumption
  • High-speed switching capability
  • Wide operating voltage range
  • ESD (Electrostatic Discharge) protection

Advantages and Disadvantages

Advantages

  • Fast switching speed enables high-speed data transfer.
  • Low on-resistance minimizes signal attenuation.
  • Wide operating voltage range allows compatibility with various systems.
  • ESD protection ensures device reliability.

Disadvantages

  • Limited number of input/output ports (16 in total).
