Description
Pericom Semiconductor’s PI3VT series of logic circuits are produced
using the Company’s advanced submicron CMOS technology,
achieving industry leading performance.
The PI3VT3245 is a 2.5V or 3.3V 8-bit, 2-port bus switch
designed with a low On-Resistance (5). The switches are turned
ON or enabled by the Bus Enable (BE) 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.
