Analog Switches - Special Purpose FAQ

What is the function of the SEL control input?

When SEL is low, Port A connects to Port B and Port C connects to Port D for pass-through. When SEL is high, Port A connects to Port D, while Ports B and C enter a high-impedance state.

What is the typical bit-to-bit skew specification?

The typical bit-to-bit skew within the same differential pair is 10 ps.

What is the maximum power dissipation rating?

The maximum power dissipation is rated at 0.5W.
