PI3VT32X245-A
16-Bit, 2-Port, Low Voltage
Translator Bus Switch
Description
Pericom Semiconductor’s PI3VT series of logic circuits are pro-
duced using the Company’s advanced submicron CMOS technol-
ogy, achieving industry leading performance.
The PI3VT32X245-A, a 2.5V or 3.3V 16-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 signals.
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.
