Analog Switches - Special Purpose FAQ

What is the function of the SEL input?

The SEL input determines the switching configuration. When SEL is low, Port A connects to Port B and Port C to Port D. When SEL is high, Port A connects to Port D and Port B to Port C.

How does the OE# pin operate?

The OE# pin is an active-low output enable. When OE# is low, the device I/O is enabled. When OE# is high, all I/O pins enter a high-impedance state.

What is the maximum operating frequency?

The device supports PCI Express 2.0 performance at 5.0 Gbps, which corresponds to a fundamental frequency of 2.5 GHz.
