Product Description
Pericom Semiconductor聮s PI3VT series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology,
achieving industry leading performance.
The PI3VT32X245, is a 2.5V or 3.3V 8-bit, 2-port bus switch, is
designed with a low ON resistance (5 ohms). 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.
Applications
聲 3.3V to 2.5V level shifting (voltage translation)
聲 2.5V to 1.8V level shifting (voltage translation)
