Description

The PCA9543ADR 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 SCn/SDn channel or combination of channels can be selected, determined by the contents of the programmable control register. Two interrupt inputs (INT0–INT1),one for each of the downstream pairs, are provided. One interrupt output (INT) acts as an AND of the two interrupt inputs. PCA9543ADR Features • 1-of-2 Bidirectional Translating Switches• Two Active-Low Interrupt Inputs• Active-Low Interrupt Output• Active-Low Reset Input• Supports Hot Insertion• Low Standby Current
