| Description | 2-channel I2C-bus switch |
|
|
The PCA9543A/43B/43C is a bidirectional translating switch, controlled by the I2C-bus. The SCL/SDA upstream pair fans out to two downstream pairs, or channels. Any individual SCx/SDx channels or bination of channels can be selected, determined by the contents of the programmable control register.
