PCA9544ABS

4-channel I2C-bus multiplexer with interrupt logic

The PCA9544A is a 1-of-4 bidirectional translating multiplexer, controlled via the I2C-bus. The SCL/SDA upstream pair fans out to four SCx/SDx downstream pairs, or channels. Only one SCx/SDx channel is selected at a time, determined by the contents of the programmable control register. Four interrup; 1-of-4 bidirectional translating multiplexer\nI2C-bus interface logic; compatible with SMBus\n4 active LOW interrupt inputs\nActive LOW interrupt output\n3 address pins allowing up to 8 devices on the I2C-bus\nChannel selection via I2C-bus\nPower-up with all multiplexer channels deselected\nLow Ron ;
