DescriptionThis dual bidirectionalI2C and SMBus voltage-level
translator, with an enable (EN) input,is operational
from 1.2-Vto 3.3-V VREF1 and 1.8-Vto 5.5-V VREF2.
The PCA9306-Q1 allows bidirectional voltage
translations between 1.2V and5V, without the usea direction pin. The low ON-state resistance (ron)of
the switch allows connections to be made with
minimal propagation delay. When ENis high, the
translator switchis ON, and the SCL1 and SDA1 I/O
are connected to the SCL2 and SDA2 I/O,
respectively, allowing bidirectional data flow between
ports. When ENis low, the translator switchis off,
anda high-impedance state exists between ports.
