General Description
The PCA9846 is an ultra-low voltage, quad bidirectional translating switch controlled via the I2C-bus.
The SCL/SDA upstream pair fans out to four downstream pairs, or channels.
Any or all SCx/SDx channels can be selected, determined by the programmable control register.
Key Features
