Description
Pericom Semiconductor’s PI3VT3306 is a 2.5V or 3.3V 2-bit,
2-port bus switch designed with a low On-Resistance (5Ω). The
switches are turned ON or enabled by the Bus Enable (BEn) input
signal.
Given a 3.3V supply and an input voltage of 3.3V, the switch
translates to an output voltage of 2.5V. Similarly, when operated
with a 2.5V supply and given 2.5V inputs, the device translates
the outputs to 1.8V.
