Signal Switches, Multiplexers, Decoders FAQ

How does the ADG3241 achieve 3.3 V to 1.8 V level translation?

Level translation from 3.3 V to 1.8 V is achieved by tying the SEL (Select) pin to Logic 0 while operating the device from a 3.3 V supply. This activates internal circuitry that clamps the output signal to approximately 1.8 V.

What is the maximum data rate supported by this bus switch?

The ADG3241 supports a maximum data rate of 1.5 Gbps when operated at a 3.3 V supply with the SEL pin tied to VCC.
