Series Information for PCA9548ADB - Texas Instruments

Description

IC ANALOG MULTIPLEXER 8 X 1 SSOP-24
The PCA9548A has eight bidirectional translating switches that can be controlled via the I2C bus. The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register. The system master can reset the PCA9548A in the event of a timeout or other improper operation by asserting a low in the RESET input. Similarly, the power-on reset deselects all channels and initializes the I2C/SMBus state machine. Asserting RESET causes the same reset/initialization to occur without powering down the part.
